I wonder if a piece of hardware, video card for example, is also needed
to trigger this issue?  Something in the kernel config maybe? 

Just a thought.  Thanks for the heads up Alan.  Nothing like expecting
something to go wrong and have a plan B handy.

My make.conf is old.  Some of the entries there could be over a decade
old.  I also have commented out a lot of really old stuff, just to see
if it does anything.   I'll go check man emerge and friends and then see
if google does anything useful.  We all know how google is.  ;-)

While at it.  Is there a tool that tells when USE flags in make.conf is
either no longer used or doesn't even exist anymore?  I googled that a
while back and didn't find anything.  I don't think the eix tools does
that either.  It does for the other /etc/portage/ files but I don't
think it touches make.conf. 

Thanks for the heads up.

You probably don't need this one any more... you'll have to consult a
lawyer to figure out what `man emerge` says on the matter, but IIRC, the

It might not be the ISP that's broken.  It might be the user's
firewall/router.  A lot of the cheap consumer models are starting to
"support" IPv6 by default when it appears to them that the ISP
supports IPv6. But, the default IPv6 firewall/router settings aren't
always usable.


I'm currently using the ISP provided router, as I don't have anything
ATM that can handle 150 mbps symmetrical.

I'm guessing the delay is due to DNS resolution missing of being misconfigured
somewhere in your/your ISPs network.  Could you tweak your router's DNS
resolver addresses to point to OpenDNS resolvers, or some such if your ISP's
are not working properly?



No, the DNS was working. It was trying to connect to a specific ipv6 
address to sync, and failing (twice.)


That's what I initially thought too, but checked name resolution and it 
was returning proper addresses.


I even thought (before I started to remove systemd from my old laptop) I 
could save time by disabling ipv6 on the ISP router (my cell phone 
suffers the same delay), but then it wouldn't even connect to their network.

Are you using openrc? It is possible it's looking for systemd to provide
the shutdown and reboot options.

If you're not using systemd, switch to the non-systemd plasma profile
and issue `emerge -auDN world`.

Dan





If openrc is being used, check out this article:

Another option (that works well for me) is to use elogind.

I do this on occasion when some update makes things go weird.  I'll look
for anyone else having the issue and if not, then I do a emerge -e world
to see if it helps. 

First, I have entries in make.conf to help make it so that it doesn't
affect what I'm doing.  I use ionice, -j and friends to do that.  I also
use --keep-going as well.  Generally, I can't tell it is doing
anything.  There is a few packages that it slows things down for a few
minutes.  It doesn't do it for the whole compile process, just a few
minutes of it.  Firefox, Libreoffice is two that I recall. I'll post
some of my make.conf items below. 

Second, you can skip certain programs, large ones for example.  You can
for example add this:  --exclude libreoffice  That will let it skip
libreoffice but keep in mind, some dependencies may be skipped as well,
if nothing else depends on them.  I haven't tested that but that's my
thinking.  Maybe someone else has more ideas on that. 

Third, I'm almost certain --resume works even after a reboot.  Just keep
in mind, if it was in the middle of a package compile, it likely will
start over from scratch.  That's my experience at least. 

Some of my make.conf entries.  You may not need all of these so edit out
what you don't want or change values if you need to.  I have a four core
CPU. 

FEATURES="-usersync -userpriv -usersandbox buildpkg sandbox parallel-fetch"

MAKEOPTS="-j5"

EMERGE_DEFAULT_OPTS="--with-bdeps y --backtrack=100 --keep-going -v -j5
--quiet-build=n -1 --unordered-display"

PORTAGE_NICENESS=5

PORTAGE_IONICE_COMMAND="ionice -c 3 -p \${PID}"

As for the command I use, emerge -ea world.  If you have to shutdown for
a while, once you reboot, try emerge --resume and see if it works.  It
should.  I've done it before but its been a good while back.

Hope that helps.

[gentoo-user] emerge --emptytree : how to ?

[Helmut Jarausch]

Hi,
I think I'm in need of doing
emerge --emptytree ...
for the first time.
Can I do it on a running Gentoo system?
I expected it will take several days to complete.
This poses some problems to me.
First, I have to shut down my machine overnight.
Second, I haven't made good experience with --keep-going
nor with --resume.
What can I do if 'emerge -e ...' fails by itself or because I have to
shut my machine down?

Many thanks for some hints,
Helmut

Radiators.  Now that is funny.  I was hopeful that one of them would

Hi Dale,

thanks for googling qcalc from "the other side" :)

The first qcalc is described as
"QCalc today is a simple calculator for the T-Mobile Hiptop, with the potential 
to be so much more."
...so since "T-Mobile" is involved it seems an app. Chances are very
small, that this a "nerds only" application, who run a linux
commandline on their phones... :)

The second qcalc is a link to a german company, which build radiator
installations and such (sorry, my english is limited). Their qcalc
is a "heat dissapation and delivery calculation software" ... very
specialized and no commandline thingy.

Thanks a lot for your googling, Sir ! :)))

[gentoo-user] sddm-0.16.0 does not work with plain openrc

[Alan McKinnon]

Hi

A quick heads-up to anyone who like me uses sddm on a plain openrc box
with USE="-elogind -systemd" and upgrades to sddm-0.16.0 (recently released)

That combination does not work. The xdm service starts, sddm launches,
logs a message that doesn't look too ominous and then does ... nothing.
No sddm, No X-Server. Very confusing, took me a while to solve.

Masking sddm-0.16.0 and downgrading back to sddm-0.15.0 restores
functionality. More info and the Gentoo bug report:
