tried the HOWTOs yet, I believe there is one on raid.
2.0.35 has RAID support, at least I got the option when I made a custom
kernel.

Yes there is. You can download the LiS STREAMS package from the
directory:
ftp://ftp.gcom.com/pub/linux/src/streams-1-30-98
In the near future we will be releasing an update that runs on the 2.2
kernels.

He didn't say, 'Make an API to a cryptic binary file', he said make an
API.
One thing that he didn't say in his response (least, if he did, I missed
it), is that with so many programs using this data, and possibly
changing this data, it would be good to have an API so that you have one
program that handles write access to the file propperly. That is, if it
needs to write to the file, everyone gets put on hold while it does so.
I've seen cases where that didn't happen, it's not pretty. Especially
when one of the processes that wants to read in the middle of a write is
pulling the file in to make its own modifications, and write them back.
Instant corrupted data.
Another way of putting what he's saying - 'Make a vipw, rather than edit
/etc/passwd directly.' Sure, vipw's pretty much useless on a
single-user machine. But in an environment with 20 system
administrators, where any of them can edit /etc/passwd, vipw suddenly
makes a lot more sense. Of course, since you've also got the new guys
in there, adduser makes more sense. Oh, my, greater API complexity.

You really think that we can't have our API reload the file without
rebooting? Bah.

No more than you have them re-read the configuration files they already
have. *Their* information will not change any more rapidly; it's just
that all the changes happen close to the same spot now.

Each time it handles a response, if it's more than <configurable time>
since it last read the configuration file, it checks the mod timestamp.

Ever hear of named pipes? (Pipes always were my special toy...)
On the other hand - so much requires networking these days; it's a
fairly standard feature. There's also the point that one's
configuration is a *lot* simpler if one doesn't have networking, this
wouldn't be nearly as needed.
Consider, without networking one doesn't have to worry about
ppp
sendmail
named
X
tcp wrappers
netscape
apache
lynx
NNTP
NTP
DHCP
FTP
You probably don't even have to worry about having a light sendmail
replacement or any mail readers. You probably don't need a newsreader,
the list goes on. I don't know about you, but the programs I've most
frequently been asked to help configure were X, pppd, and sendmail.

Maybe better people are working on them, and we'd only get in the way.
Not to mention, if I'm going to cut down on my admin time, I get
something back from this. The only time I get some added time back from
my kernel hacks is when it saves me from reboot or catastrophic
recovery. So far, it never has. (Admittedly, until recently, I've
never even considered my kernel hacks worthy in any significant way.)

This program makes my computer sleep 2 times for 100 seconds each. I
can switch to another console and type commands (and see what I type),
but nothing happens until the fsync() finishes.
I'm using Linux 2.2.0-pre5, Symbios 53c860 and IBM DDRS-39130.

No, you're just very dependent on their property.

Redhat doesn't retain singular ownership of anything.
If they did, they would be no less dangerous than
Troll or Microsoft.

Subject: mounting ufs filesystems read/write

Reply-To: [EMAIL PROTECTED]
I have a PC, installed Solarisx86 release 2.6, MS Windows NT and Redhat 5.2 on it.
I wish to access my Solaris partitions from linux.
I just finished installing kernel 2.2.0-pre4.
I compiled the kernel not using modules (because I'm afraid it interferes with my
2.0.36 installation),
with UFS filesystem support and Solaris x86 patition table support.
After booting, 'dmesg' nicely reports my Solaris partitions:
Partition check:
hda: hda1 hda2 <solaris: [s0] hda5 [s1] hda6 [s2] hda7 [s5] hda8 [s6] hda9 [s7] hda10
> hda3
hdc: hdc1 hdc2 <solaris: [s2] hdc5 [s4] hdc6 [s5] hdc7 [s6] hdc8 [s7] hdc9 > hdc3
hdc4 < hdc10 >
Succeeded to mount hdc9:
mount -v -t ufs -o ufstype=sun /dev/hdc9 /tmpmnt
output:
/dev/hdc9 on /tmpmnt type ufs (rw,ufstype=sun)
Reading all files on the partition is possible, but touching a file on it results in:
touch: /tmpmnt/wim/wimpy: Read-only file system
Did anybody manage to mount ufs filesystems read/write?

Its not loading my modules and doesn't work correctly after boot. I
copied the System.map file over too /boot/ and changed the symlink to

to get it too load the modules still it does not. What am I missing

Jedi, your grasp on reality is starting to look... inadequate.
I would be very very surprised if the software written by Red Hat
employees on work time didnt have a nice "copyright by Red Hat" sign on
it.
Red Hat does own the code they create, just like Troll Tech and Microsoft.
That you have a copy of it under the GPL doesn't mean they can't later
re-release it under a proprietary license.
Yes, jedi, just like you always said Troll Tech would do (and apparently you
still think so). Of course I don't think Red Hat will, just like I knew TT
wouldn't, but then again I don't live in that dark world you live in.
BTW: same argument works with the FSF. The only code owner I know that
has made legal arrangements for this not to happen is Troll Tech. Amazing,
isn't it?
