  cannot use kmail, or no KDE4 at all. And have to invest time to solve

  unstable, and taking 5 minutes to start. What the heck is it doing in
  this time?
 
 Fuck knows what amarok-2x does for the first 5 minutes. I *think* On my
 system it scans the music directory, presumably to find updates that
 happened when amarok was not running. Fair enough, can't argue that,
 but why is it so *slow*???

Yes, it scans the collection, I just verified that by removing a folder 
from my collection. Start-up takes 7 minutes, I guess this also slows down 
my KDE4 start-up even further (strigi also scans some stuff for about a 
minute, along this music files I did not touch in any way). So when I save 
my KDE session I have to remember to quit amarok before that. Of course, I 
also have to remember to start amarok some time after I logged in, so I 
can play music when I want without having to wait 7 minutes first.

This does not feel right...

BTW, a find /data/mp3 -type d takes about a minute. Checking the date of 
the directories to verify they did not alter since the last scan should 
not take that much longer.

Ah, I see the problem. It mainly scans /data/mp3/incoming, a directory I 
have NOT selected as collection folder (but most other directories in 
/data/mp3 are selected). Still, those files do not show up in my 
collection, which is fine - some time ago amarok did index all in 
/data/mp3, even if a directory was not selected.


 Fuck also knows what the amarok devs are doing in general. I still
 can't find a way to move stuff to an mp3 player like the old 1.4
 version did. And the library thingamagij still doesn't always update
 tags, or put tag changes that it itself did into it's own database. It
 gladly accepts any changes you make in the Edit Tags dialog, and tries
 to write them, even if it knows it cannot do it (no support for that
 format, permissions, etc). Then, no warning or message about this.

Ah, this looks familiar, I ran into this, too.

 Depending on which bleeding edge latest-svn commit build you happen to
 get on any given day, this last might or might not tell you something
 in the status bar.

I'm always using the newest version that is not hard-masked. with every 
new version, some things get better, but others get worse. This delays and 
startup times are new to me, but on the other hand I did not get any file 
corruption for a long time.
I do not like the new toolbar though. Where are the stop, forward and back 
buttons? And for the volume control I have to move the mouse in a circle 
around it... or use the scroll wheel, okay. Nah, I liked it better the way 
it was before.


 For all the above reasons, and more, I have switched to clementine
 (it's in portage). It's a Qt port of amarok-1.4 and has equivalents of
 all the music- playing goodness that amarok used to have. It doesn't
 do tags, external players, wikipedia etc etc, it just plays music. And
 you have to tag your music by other means with eg kid3. I can live
 with that. At least it starts and stays up.

Nice! But not for me. I like the wikipedia stuff. And tagging, now that it 
seems to work. And what amarok is supposed to become. Yes, I like it much 
better than the old amarok, it's just that things do not already work 
fine. So I will keep suffering, until some day amarok will not do all the 
annoying stuff it currently does. The day will come! Hopefully long before 
they start coding amarok-3 and all gets worse again. I'll just have to 
wait. And wait.

Thanks anyway for the tip, at least I can use clementine when I see that 
amarok is not running yet and did not do its 7 minutes of scanning 
already.

[gentoo-user] Filesystem corruption - reiserfs? - won't boot, filesystem couldn't be fixed :(

There seem to have been a few people posting with filesystem  
corruption in the last week or two. It seems to be my turn, so I hope  
it isn't contagious. The cause here is quite clear - whilst rummaging  
in the server cupboard yesterday, power to the machine was  
accidentally disconnected.


I have booted with a live CD  run `reiserfsck --fix-fixable` on the  
filesystem, but nevertheless when I attempt to boot the system I get a  
failed to open the device... no such file or directory message,  
followed by another error as per subject line.


However, you will see from this screenshot (taken with an IP KVM) that  
the filesystem does indeed seem to have been mounted successfully, if  
read-only:


http://linux.stroller.uk.eu.org/fs-corruption.png

All I did here was log in with the root password.


When I boot with a live CD I can mount, read  write the filesystem:

r...@sysresccd /root % mount -v -L root /mnt/gentoo
mount: you didn't specify a filesystem type for /dev/sda3
   I will try type reiserfs
/dev/sda3 on /mnt/gentoo type reiserfs (rw)
r...@sysresccd /root % ls /mnt/gentoo
bin  boot  dev  etc  home  lib  mnt  opt  proc  root  sbin  sys  tmp   
usr  var

r...@sysresccd /root % touch /mnt/gentoo/foo
r...@sysresccd /root % echo foobar  /mnt/gentoo/foo
r...@sysresccd /root % ls -lh !!:$
ls -lh /mnt/gentoo/foo
-rw-r--r-- 1 root root 7 2010-03-03 11:18 /mnt/gentoo/foo
r...@sysresccd /root % cat !!:$
cat /mnt/gentoo/foo
foobar
r...@sysresccd /root % rm !!:$
rm /mnt/gentoo/foo
rm: remove regular file `/mnt/gentoo/foo'? y
r...@sysresccd /root %

All the important system stuff on this PC is on a single partition. I  
have two other drives attached at /mnt/space  /mnt/morespace - they  
are XFS and I have run xfs_repair on both of them, which completes  
quickly indicating no problems.


I'm not really sure how to proceed next. I feel the problem is indeed  
on this reiserfs filesystem, the root filesystem with the label  
root. I can't help thinking that the problem is not that the system  
failed to open the device, but instead maybe that there's an  
important system file missing that means the init script (or whatever  
responsible for mounting the fiesystem) is not properly returning 0.  
Does this seem possible? Maybe the reiserfs handler for mount is  
somehow broken (performing the mount, but not returning 0, or perhaps  
broken in such as was it is able to mount read-only but not read-write).


I am tempted to chroot into the system and re-emerge system   
baselayout. If I'm correct in this above guess then re-emerging the  
correct file   will fix the problem. Right?


`reiserfsck --help` shows some other options besides the simple --fix- 
fixable - I assume the expert option of --scan-whole-partition is  
unsafe, but what about the --rebuild-sb or --rebuild-tree? Can I  
safely run these? Am I advised to run these?

You mean the other way around, right? reiser defaults to tail-packing,
which can cause problems with GRUB and LILO, which is why notail is an
option which turns off tail-packing for those crazy enough to use
reiser on /boot. 

If you use notail on the portage tree, you get rid of that advantage,
then Neil is absolutely correct: there's not too much point in
journaling the portage tree, and if you actively make reiser
not-competitive on the storage-space direction, the only metric left
to compare is speed, and ext2 is faster. 

Incidentally, if you are willing to sacrifice speed for space, then a
sparsefile for /usr/portage may also be an option.

They benefit compared with using reiser with tail-packing.

 Did you change the block size?

I had to change both the block size and blocks per inode, otherwise I
would run out of inodes on a 1GB filesystem. You have to admire the
user-friendliness of ext!

  There's no need for journalling on the portage tree, it's small enough

 I also had used ext2 for my portage tree first, then I read somewhere
 that reiserfs would be the best. BTW, I have distfiles and pkgdir
 somewhere else, if not the fsck would not be so fast.

It's certainly noticeable compared with ext3. Many benchmarks do show
ext2 to be the fastest filesystem, probably because of the lack of
journalling overhead.

Like you, I have $DISTDIR and $PKGDIR elsewhere, those files really
should not be mixed in with the portage tree.

 Just for fun, I just copied my $PORTDIR into my tmpfs, emerge -DpN
 @system @world takes between 81 and 53 seconds. With reiserfs, I get
 130 seconds first ($PORTDIR was unmounted first and mounted again to

 I had expected that tmpfs would be even faster. I think I just keep it
 the way it is now.

The exact same thought occurred to me. With a local tree to sync from,
tmpfs seemed a good choice (you could sync it from /etc/conf.d/local) but
it seems like it is not worth bothering with. I'll try a reiser3
filesystem without tail packing to see if it beats ext2.

I was surprised that three major social networking sites have dumped

it.  Maybe nobody trusts Oracle?


I read the other day that Facebook have NOT dropped MySQL - they  
remain committed to it - but that they use NoSQL technologies for some  
of their queries as it is more scalable. This seems to concur with an  
update to the article, which not everyone may have seen.


Unless they are using closed-source modules to MySQL (do these exist?)  
the Oracle situation probably would not worry such large companies are

I concur. /usr has a long tradition is Unix of often being mounted read-only 
(think thin clients that mount it over NFS).

My set up is:

portage:/var/portage/
my overlay: /var/portage/local/alan/
layman: /var/portage/local/layman/*

As portage is hard-coded to not fiddle with $PORTDIR/local/, this works well 
for me and every ebuild on the system is under one mount point.

from the output it looks like you are mounting by label? What if you
edit fstab to point to the device name /dev/hd?? instead of
LABEL=root? Check the filesystem label to make sure it is ok?


Many thanks for this suggestion, however following it makes no  
difference, except in the trivia that it says failed to open the  
device '/dev/hda3': No such file or directory (instead of LABEL=...).


I also tried editing grub to point to /dev/sda3 (although admittedly  
with the LABEL= entry in /etc/fstab) but that makes no difference. I  
have never tried (intentionally) reconfiguring this kernel to use /dev/ 
sdX instead of /dev/hdX and I'm pretty sure it's booted using the  
current kernel  configuration in the past.

 The cause here is quite clear - whilst rummaging in the server cupboard
 yesterday, power to the machine was accidentally disconnected.

 I have booted with a live CD  run `reiserfsck --fix-fixable` on the
 filesystem, but nevertheless when I attempt to boot the system I get a
 failed to open the device... no such file or directory message, followed
 by another error as per subject line.

 However, you will see from this screenshot (taken with an IP KVM) that the
 filesystem does indeed seem to have been mounted successfully, if read-only:

 http://linux.stroller.uk.eu.org/fs-corruption.png

 All I did here was log in with the root password.


 When I boot with a live CD I can mount, read  write the filesystem:

 r...@sysresccd /root % mount -v -L root /mnt/gentoo
 mount: you didn't specify a filesystem type for /dev/sda3
       I will try type reiserfs
 /dev/sda3 on /mnt/gentoo type reiserfs (rw)

 cat /mnt/gentoo/foo
 foobar
 r...@sysresccd /root % rm !!:$
 rm /mnt/gentoo/foo
 rm: remove regular file `/mnt/gentoo/foo'? y
 r...@sysresccd /root %

 All the important system stuff on this PC is on a single partition. I have
 two other drives attached at /mnt/space  /mnt/morespace - they are XFS and
 I have run xfs_repair on both of them, which completes quickly indicating no
 problems.

 I'm not really sure how to proceed next. I feel the problem is indeed on
 this reiserfs filesystem, the root filesystem with the label root. I can't
 help thinking that the problem is not that the system failed to open the
 device, but instead maybe that there's an important system file missing
 that means the init script (or whatever responsible for mounting the
 fiesystem) is not properly returning 0. Does this seem possible? Maybe the
 reiserfs handler for mount is somehow broken (performing the mount, but not
 returning 0, or perhaps broken in such as was it is able to mount read-only
 but not read-write).

 I am tempted to chroot into the system and re-emerge system  baselayout. If
 I'm correct in this above guess then re-emerging the correct file   will fix
 the problem. Right?

 `reiserfsck --help` shows some other options besides the simple
 --fix-fixable - I assume the expert option of --scan-whole-partition is
 unsafe, but what about the --rebuild-sb or --rebuild-tree? Can I safely run
 these? Am I advised to run these?

 Stroller.

Hi Stroller,
   Sorry for your problems. I've had a rash of machine problems over
the last 6 weeks. No fun. I feel for you.

   In my most recent case what looked like a simple disk corruption
problem was really a prelude to the drive just plain going bad. Have
you tried smartctl to see what it says about the drive at this point?

   It would be even more frustrating to chroot in, do all the work,
think you had it fixed and then the underlying foundation of your
house crumbles beneath you 3 weeks from now.

Good luck,
Mark

In my experience reiserfs is a very stable fs.  I had a dodgy memory
module once which I put up with for more than 9 months.  The machine
would lock up hard on a daily basis and the only way to get it going
again would be to pull the plug.  That would happen at random,
midstream emerge --sync, package updates, updatedb, etc.  It survived
through hundreds of crashes by fsck at the next boot.  Once or twice
things went hairy and I would get a message similar to yours.  On
these rare occasions I booted with a LiveCD and with the partitions
unmounted I ran --check, then --fix-fixable and finally
--rebuild-tree.  You may want to use an external drive with dd to
image the current / partition and do all your recovery work on that.
If you don't care too much about the risk of catastrophic failure then
just run --rebuild-tree with a LiveCD and see what you get.

Good luck.

This looks to me like smartctl is going OMG! What an ancient drive!  
- it's a 20gig EIDE drive and if my pocket calculator is correct  
(44803/24/365), it's seen 5 years of active use - and that's the  
marginal attribute referred to.


Like I said, the power plug was accidentally pulled on this drive, so  
I'm inclined to attribute the corruption only to that, not to the  
drive actually failing.


The drive is in a computer that has rarely been turned off in the last  
couple of years, and is also in a warm environment, conditions which  
are ideal. I appreciate the latter seems unintuitive, but in fact  
studies have showed that drives in somewhat warm environments last  
longer than those that are cooled.


That it passes the SMART overall-health self-assessment test  
suggests to me that it is chugging away quite happily.


I would have dismissed your concerns were it not for the capitalised  
FAILING_NOW in the output. Like I say, I think this is just smartctl  
declaring OMG! this drive is old!, but I open this matter to the  
list for discussion (should you wish).


I think I'm actually nearly ready to migrate off this system. The  
power was actually pulled as I installed 3 new (to me) rackmount  
machines in the server cupboard - the plan is to have identical  
machines running RAID, so that in the case of ANY problems I have  
spares available. I have take nightly backups of the important data on  
this machine, however I'd prefer it to run just a couple or a few  
weeks longer to allow me to migrate at my own leisure.

If you try to boot, after the failure to check rootfs, it should dump

 Stroller.

I've had two machines go bad due to hard drive problems in the last 6
weeks. One drive was 4.5 years old, the other 6 years old. I have no
experience with smart. I'm just learning about it. However it is
generated by the microcontroller in the hard drive as per the view of
the drive manufacturer so if the drive is telling you it's failing
then...

My 4.5 year failure actually stopped producing smart output somewhere
along the way before it failed. The 6 year drive I wasn't using smart
at the time so I had no data from it but it was in an environment
where the UPS went through a lot of abuse.

I sounds like you have good backups so just make sure they are good
and do what you want.

[gentoo-user] Advice for 64-bit n00b?


Hi there,

A new (to me) server has 64-bit CPUs. By my standards this is a REALLY  
NICE high specification machine (I appears to be 2 x dual-core), but  
in fact it's about 3 years old  is one of the earliest Intel Xeons  
that supports 64-bits / AMD64 / EMT64. I think it is 64-bit Pentium 4,  
rather than Core 2 architecture.

Is there anything I need to know about working with 64-bits / AMD64 /  
EMT64, seeing as I've never done so before?


I have started following the Gentoo Linux AMD64 Handbook, because the  
Quick Install Guide is described as x86. Having untarred the stage I  
am surprised to find a lib32 directory. I thought compatibility with  
32-bit binaries was optional. Or am I misunderstanding? This is going  
to be a headless server  I can't think that it'll need any binary  
packages - possibly the management utility for the RAID controller  
will be distributed as a binary, I'm not sure yet (the hardware RAID  
key was missing when I got this machine ☹)


I'm editing my make.conf and looked at the Gentoo wiki for Safe  
Cflags - it says 'CHOST=x86_64-pc-linux-gnu'. But of course  
(according to make.conf.example) one shouldn't change CHOST on an  
installed system. Will the files in the stage 3 have been compiled  
using this CHOST?


Any pointers would be gratefully appreciated - I'm wondering if  
there's anything you guys all take for granted that I could mess up if  
I don't allow for it early enough in the installation process.


Thanks in advance for any comments,

Stroller.

 (according to make.conf.example) one shouldn't change CHOST on an
 installed system. Will the files in the stage 3 have been compiled
 using this CHOST?

Yes. If you used a recent amd64 stage, it will all be fine.
 
 Any pointers would be gratefully appreciated - I'm wondering if
 there's anything you guys all take for granted that I could mess up if
 I don't allow for it early enough in the installation process.

In make,conf, as long s you are using a reasonably recent gcc:

CHOST=x86_64-pc-linux-gnu
CFLAGS=-march=native -O2 -pipe
CXXFLAGS=${CFLAGS}


-march=native avoids all that tedious mucking about with trying to figure out 
what cpu type you should build for, and moves the heavy lifting off onto the 
compiler.

 KDE wants to create a Desktop and a Desktop-1 directory. I want it to just use

Can you symlink Desktop-1 to Desktop? ( I only have 1 monitor and have

 They benefit compared with using reiser with tail-packing.

Oh my. I have it the other way around, and never even thought much about 
what this does.

  Did you change the block size?
 
 I had to change both the block size and blocks per inode, otherwise I
 would run out of inodes on a 1GB filesystem. You have to admire the
 user-friendliness of ext!

I only wished I could add more inodes after all are out, because this 
happens quite frequently to me. But yes, it's nice I can specify this at 
all.


   There's no need for journalling on the portage tree, it's small
   enough to fsck quickly and if it does get broken, reformat and
   resync.
  
  Would the journaling overhead be noticeable?
  I also had used ext2 for my portage tree first, then I read somewhere
  that reiserfs would be the best. BTW, I have distfiles and pkgdir
  somewhere else, if not the fsck would not be so fast.
 
 It's certainly noticeable compared with ext3. Many benchmarks do show
 ext2 to be the fastest filesystem, probably because of the lack of
 journalling overhead.

When I saw some, it was maybe 15% difference, and that probably due to 
writes I assume. The portage tree is written during sync only, and then I 
do not care about speed. But would accessing lots and lots of small files 
be slowed down by journaling?

 Like you, I have $DISTDIR and $PKGDIR elsewhere, those files really
 should not be mixed in with the portage tree.
 
  Just for fun, I just copied my $PORTDIR into my tmpfs, emerge -DpN
  @system @world takes between 81 and 53 seconds. With reiserfs, I get
  130 seconds first ($PORTDIR was unmounted first and mounted again to
  clear the caches), and 57 seconds in the second attempt.
  
  I had expected that tmpfs would be even faster. I think I just keep
  it the way it is now.
 
 The exact same thought occurred to me. With a local tree to sync from,
 tmpfs seemed a good choice (you could sync it from /etc/conf.d/local)
 but it seems like it is not worth bothering with.

I would need more memory for that, I'm not at amd64 yet. But I probably 
should migrate anyway, and get another 4GB of memory.

 I'll try a reiser3
 filesystem without tail packing to see if it beats ext2.

I backed up my portage tree, re-created the reiserfs partition, and 
mounted without notail option. The same emerge command now takes about 
three minutes... no, on 2nd try it's five. Hmm... ah, clementine is 
indexing files. Why does it do this, I did not change files. Oh, and it 
has indexed all of my /data/mp3, while I only gave it four subfolders to 
index. Why does no audio player just accept my choices for what the 
collection is, and add other stuff?

The next test gives 93 seconds, that's nice.

Oh dear. Yes. Thanks.

 reiser defaults to tail-packing,
 which can cause problems with GRUB and LILO, which is why notail is an
 option which turns off tail-packing for those crazy enough to use
 reiser on /boot.
 
 If you use notail on the portage tree, you get rid of that advantage,
 then Neil is absolutely correct: there's not too much point in
 journaling the portage tree, and if you actively make reiser
 not-competitive on the storage-space direction, the only metric left
 to compare is speed, and ext2 is faster.
 
 Incidentally, if you are willing to sacrifice speed for space, then a
 sparsefile for /usr/portage may also be an option.

I had this once on a smaller machine, but now I'd prefer it the other way 
around, there's plenty of space available. I have 15G for distfiles and 
pkgdir, so I don't worry about some 100MB for the portage tree.

/usr/src/ is the traditional place for kernel header files. They are intended 
to be static, change seldom, and definitely not something that users can 
change. Normally, root would update them when needed, and stuff can then build 
against them.

/usr/share/config/ is an upstream thing and if you follow FHS then /etc/ is a 
better place. But Gentoo follows upstream as much as possible so this one gets 
left as-is.

NB: Gentoo only follows FHS when it suits Gentoo devs to do it :-) The 
reasoning offered is usually that Gentoo is a source distro and therefore has 
little needs of FHS, which does tend towards compatibility between binary 
distros

  portage:/var/portage/

 Yes, it scans the collection, I just verified that by removing a folder

 my KDE4 start-up even further (strigi also scans some stuff for about a 
 minute, along this music files I did not touch in any way). So when I save

 can play music when I want without having to wait 7 minutes first.
 
 This does not feel right...
 
 BTW, a find /data/mp3 -type d takes about a minute. Checking the date of 
 the directories to verify they did not alter since the last scan should 
 not take that much longer.
 
 Ah, I see the problem. It mainly scans /data/mp3/incoming, a directory I 
 have NOT selected as collection folder (but most other directories in 
 /data/mp3 are selected). Still, those files do not show up in my 
 collection, which is fine - some time ago amarok did index all in 
 /data/mp3, even if a directory was not selected.

I wonder if amarok would not be better off using the strigi/nepomuk indexing 
function, instead of trying to be real clever and doing it itself.

OTOH, that might just resurrect the mother of all threads we had recently -

[gentoo-user] No more mythtv for Gentoo users?

When upgrading a machine today, I saw a notice that mythtv 0.21 has
now been hardmasked.  I think it's because it depends on an obsolte
version of Qt.  Don't get me started on the royal PITA of requiring
that Qt be installed for a backend-only setup on a server.

Since 0.21 and 0.23 is hardmasked, and mythv 0.22 is unstable on
everything except the amd64 platform, what's an X86 user to do?

It probably just goes back to a snap descision by Daniel Robbins a

At one time he wasn't intending to distribute in the same way -  
Portage evolved from a script that he wrote to help him build a binary

Further to Alan's reply, I've proceeded a little further.

I'm onto section 2.3: Changing profiles, where it says:
If you want to have a pure 64-bit environment, with no 32-bit
applications or libraries, you should use a non-multilib profile.

See my comments in the quoted above. It shouldn't be too expensive to
enable the RAID in this machine (which is on the mainboard, but
requires a little hardware PCB key to be fitted). That's a Dell
PERC4, which AFAICT is a rebadged LSI megaraid.

This post [1] http://tinyurl.com/3dzcl9 referrs to the management
utility thus: MegaCLI comes as a RPM containing only a single
statically linked 32-bit Linux binary, however `eix mega` suggests
there may be alternatives, such as `megactl` [2]

My immediate thought when reading the handbook was that it's best

2010-03-03 Thread Harry Putnam

I'm having trouble when revdep-rebuild tries to emerge
dev-perl/DBD-mysql

I can't really make much sense of the output but I see it involves
scripting from perl-5.8.8 

I've included the tail of the emerge below, and below that the output
of emerge --info =dev-perl/DBD-mysql-4.01.3 as suggested by emerge output.
 
I did run `USE=build emerge -v DBD-mysql' as suggested somewhere in
the ouput.  The tail below is from that:

[gentoo-user] Boost emerge: bjam-1.41 using 100% CPU

I did an update to day on two systems.  Both are installed
boost-1.41.0-r3, and both paused during the install phase for about
ten minutes with bjam-1.41 using 100% of the CPU time.

Eventually, things become un-jammed and various files get copied to
the proper destiantions.

Is this behavior normal?

Re: [gentoo-user] KDE? Get me out of here!

2010-03-03 Thread stosss

 I wonder if amarok would not be better off using the strigi/nepomuk indexing
 function, instead of trying to be real clever and doing it itself.

I think Amarok uses MySQL.

AFAIK it is on the Amarok to-do list now that the speed is good enough
to replace mysql, but nobody has volunteered to take on the challenge
yet.

I think there's also the potential problem of users who don't install
or enable the indexing/semantic-desktop stuff might not be able to use
Amarok then...

Is that the same as you see in the dev directory of your root filesystem

  Ah, I see the problem. It mainly scans /data/mp3/incoming, a
  directory I have NOT selected as collection folder (but most other
  directories in /data/mp3 are selected). Still, those files do not
  show up in my collection, which is fine - some time ago amarok did
  index all in /data/mp3, even if a directory was not selected.

I investigated this further. Amarok seems to look for all playlists below 
/data/mp3, and then looks up all of their files. No idea why.

 I wonder if amarok would not be better off using the strigi/nepomuk
 indexing function, instead of trying to be real clever and doing it
 itself.

Strigi also keeps indexing parts of my /data/mp3 stuff with EVERY login.

 OTOH, that might just resurrect the mother of all threads we had
 recently - the one about the pros and cons of nepomuk and
 semantic-desktop :-)

I am pro, I like it, but again it seems those things are not yet working 
right. Strigi indexes stuff over and over again at every login. virtuoso-t 
then also runs for a while and hogs resources. dbus-daemon uses 10-15 
percent of CPU time according to top. Should it do this?

I enabled auto-login for KDE, so when I boot the system, at least things 
are already indexed when I start working with it.

Now I'm going to emerge KDE-4.4.1, let's see what this will change.

You are already using latin1 throughout your database? You are lucky
if that's true. It isn't for me but I've been running myth for about 4
years now.

I would suggest that if you use __any__ remote frontends and there is
any chance of someone else powering one up and using Myth then you
should first emerge -C mythtv on ALL frontend-only machines, upgrade
your server, emerge mythtv-0.22 on one frontend, make sure it works,
and then move on with any other machine.

Good luck and report back how it goes!

Amarok definitely uses MySQL, but that's the storage function, we are talking 
about the search function. 

It uses MySQL in the most brain-dead way anyone ever heard of, a way that no-
one in their right mind would consider even half-way sane.

It *requires* you to jump through interminable loops at build-time because it 
wants, wait for it, shared embedded libraries. I mean, wtf? That's not 
something MySQL was built to do. It's like having sex to preserve virginity

Then, to top it all, the Qt db libs get used wrongly too, causing the db to

  misunderstanding? This is going to be a headless server  I can't
  think that it'll need any binary packages - possibly the management
  utility for the RAID controller will be distributed as a binary, I'm
  not sure yet (the hardware RAID key was missing when I got this
  machine ☹)
 
 Further to Alan's reply, I've proceeded a little further.
 
 I'm onto section 2.3: Changing profiles, where it says:
If you want to have a pure 64-bit environment, with no 32-bit
 applications or libraries, you should use a non-multilib profile.
 
 See my comments in the quoted above. It shouldn't be too expensive to
 enable the RAID in this machine (which is on the mainboard, but
 requires a little hardware PCB key to be fitted). That's a Dell
 PERC4, which AFAICT is a rebadged LSI megaraid.
 
 This post [1] http://tinyurl.com/3dzcl9 referrs to the management
 utility thus: MegaCLI comes as a RPM containing only a single
 statically linked 32-bit Linux binary, however `eix mega` suggests
 there may be alternatives, such as `megactl` [2]
 
 My immediate thought when reading the handbook was that it's best
 and cleanest and more right to only have 64-bit libraries on a 64-
 bit system, but this need for the RAID management utility is making me
 wonder if that would be cutting off my nose to spite my face.

It has a single statically linked binary. Which probably means it already 
contains everything you will need and will run just fine. No need to build 
everything multilib; if you do need a 32bit lib, just install the appropriate 
emul-x86-linux package.

 You are lucky if that's true. It isn't for me but I've been running
 myth for about 4 years now.

I've been running Myth for a while (6 years?), but this database was
created about 7 months ago when I switched from a dedicated FE/BE
machine running KnoppMyth to a split FE/BE setup where the BE runs on
a non-dedicated Gentoo machine.  Not sure how it ended up this way
other than the fact that I don't have UTF support enabled on that box
(at some point in the past, having UTF support enabled broke something
else, but I don't remember what).

 I would suggest that if you use __any__ remote frontends and there is
 any chance of someone else powering one up and using Myth then you
 should first emerge -C mythtv on ALL frontend-only machines,

The FE doesn't run Gentoo, it runs MiniMyth -- I _think_ all I need to
do is replace the 0.21 rootfs on the USB flash drive with the one
containing 0.22...

 upgrade your server, emerge mythtv-0.22 on one frontend, make sure it
 works, and then move on with any other machine.

 I read the instructions for fixing the broken database encoding, but
 it appears mine is fine -- so updating to 0.22 won't be quite as

Good stuff. Not true for me.


 You are lucky if that's true. It isn't for me but I've been running
 myth for about 4 years now.

 I've been running Myth for a while (6 years?), but this database was
 created about 7 months ago when I switched from a dedicated FE/BE
 machine running KnoppMyth to a split FE/BE setup where the BE runs on
 a non-dedicated Gentoo machine.  Not sure how it ended up this way
 other than the fact that I don't have UTF support enabled on that box
 (at some point in the past, having UTF support enabled broke something
 else, but I don't remember what).

 I would suggest that if you use __any__ remote frontends and there is
 any chance of someone else powering one up and using Myth then you
 should first emerge -C mythtv on ALL frontend-only machines,

 The FE doesn't run Gentoo, it runs MiniMyth -- I _think_ all I need to
 do is replace the 0.21 rootfs on the USB flash drive with the one
 containing 0.22...

You've probably read this elsewhere but apparently an older 0.21
frontend can corrupt the MythTV database. Maybe it won't happen for
you if you're already using all latin1 everywhere. I'm not so I have
to be careful.

Cheers,
Mark

  Further to Alan's reply, I've proceeded a little further.
 
  I'm onto section 2.3: Changing profiles, where it says:
 If you want to have a pure 64-bit environment, with no 32-bit
  applications or libraries, you should use a non-multilib profile.
 
  See my comments in the quoted above. It shouldn't be too expensive to
  enable the RAID in this machine (which is on the mainboard, but
  requires a little hardware PCB key to be fitted). That's a Dell
  PERC4, which AFAICT is a rebadged LSI megaraid.

  there may be alternatives, such as `megactl` [2]
 
  My immediate thought when reading the handbook was that it's best

  bit system, but this need for the RAID management utility is making me
  wonder if that would be cutting off my nose to spite my face.
 
 It has a single statically linked binary. Which probably means it already
 contains everything you will need and will run just fine. No need to build
 everything multilib; if you do need a 32bit lib, just install the
  appropriate emul-x86-linux package.

So how 'safe' is it these days to build a 64bit only system?  Would you end up 
having to rebuild with multilibs because many apps which won't work on a pure

no, it is not safe to have a 64bit only system. Just choose the multilib

You didn't understand the question Volker was replying to.  The question 
was not about safe as in security, but rather safe as in I can 
rest assured that a no-multilib system can run every software I could

For an NX-based client/server that supports SSH keys, you might want

I completely misread that, I read it as it is safe to have a 64bit only 
system.

I ran a no-multilib profile for a couple of weeks which ran fine. This isn't a 
long period of time, I know. But I had absolutely no issues in that period. The 
only reason I switched back to a multilib profile was because a math program 
for school couldn't connect to it's core functions on a pure 64-bit 
environment. 
Furthermore, I have multilib flag disabled as standard, but there are some 
things (gcc, glibc mainly) where I have set the multilib flag. And I'm not 
having any sort of problem with it.

It's not unsafe in that the machine cannot work, it's unsafe in that for a 
normal desktop user's range of apps, some thing might be impossible to get 
going.

If you have a no-multilib desktop profile, and you need to install some thrid 
party app like VPN software that is 32 bit, you are stuck needing a reinstall 
(as that profile switch on a live machine is not easy nor advised).

Just be safe as use the profile that will let you use 32 bit libs if and when 
you need them.

4.4 is as safe to use as 4.3 (or equally broken depending on your point of 
view).

If you run an arch machine, then remove all the KDE stuff out of 
package.keywords and let emerge -avuND world do it's thing. Don't try and run 
unstable KDE on a stable machine, you end up with too much stuff in ~arch.

If you run an ~arch machine, then do nothing and let emerge -avuND world do
