Something must have happened.

Somebody once asked me the similar question. If this only happens after starts
up
it is probably that updatedb is running (used for locate). This is kicked off
using anacron and can be

Subject: Problem with keyboard layout under Suse
Date: Fri, 6 Apr 2001 11:32:11 +0200
Hello,
I can't seem to set the correct keyboard map under Suse 7.1
I have a belgian keyboard, an intel 102 type.(azerty)
A have tried to set my keyboard under Sax2. I get the 'correct' keymap, but
I can't type an '@' for example. Normally I have to do 'alt gr' + 2. It's
the 2 above the 'z' key (not the numeric pad).
I have tried it with the panel that comes with gnome (GKB international
keyboard), but that didn't work either. Al characters that require a
combination with the 'alt gr' key don't work.
Any ideas?

Subject: software raid1 + reiserfs + boot questions
Date: Fri, 06 Apr 2001 10:26:42 GMT
Hello,
I got it running (hooray :-) ). I have several software raid1's on ide
containing everything except /tmp and swap. I'm running this with a
patched 2.2.18 on debian 2.2 / i386. All filesystems inside the
raidvolumes except /boot, which is ext2, are reiserfs.
I have a problem though. I don't know what the correct way to reboot is.
If I reboot as I used to do, with ctrl-alt-del, then all the way at the
end of the shutdown I get a bunch of messages from the raid volumes that
seem like errors, and when I restart afterwards, the reiserfs partitions
do a log replay (which can't be normal, right?).
If I go single-user, and unmount all filesystems (except / , which is
reiserfs on raid too, as I don't know how to unmount the root filesystem
while you're still running), then only / does a log replay.
So my guess is that I'm screwing up somewhere, but I have no idea what
could be wrong. I've checked in the shutdown scripts and the filesystems
are unmounted before the raid is stopped. Is the problem perhaps that
reiserfs doesn't unmount fast enough, and the raid volumes stop before
the partitions are completely unmounted ? Or is it because the reiserfs
partitions get remounted read-only, and reiserfs takes that as an
indication that something must be wrong and does a log replay to make
sure?
The strange thing is that /boot, which is ext2 on raid, DOESN'T give
errors (or fsck's for that matter) on reboot.
The bootup problems are the only strange thing, because otherwise it's
performing as it should.
Please reply to both newsgroup and sender,
thank you,

Anyway, I'd suggest that you change 'ps -u nknight' tp 'ps -lu nknight' and

If that's what makes python better than C, then that must be what makes
C++ better than C, because you can say those remarks for both python and
C++. Okay okay, I'll admit the clear syntax thing is dependant on the

I disagree. I've co-written a large project in C++, and although at
first I believed it to be unbelievably complex (coming from a Delphi
environment), later on I understood that everything is in there for a
reason. Nobody forces you to use ALL of C++ in one program.
If Python is like a grocery store, quick to reach, and with good
service, then C++ is like a supermarket, at first you're lost, but once
you find your way around and learn what the shortcuts are, it is
incredibly more powerful than a grocery store can ever be. And it also
offers more products :-)
Ofcourse, knowing my luck I'm talking to a C++ veteran. But it's
honestly my opinion. C++, when used correctly, is not complex at all.
Unless you bring GUI's into the picture ;-) Although I must admit that I
still like Delphi better than C++.
have a nice day,

I agree with you: it should have worked. A couple things...
1. I assume you rewound the tape between the "dump ... /home" and the
"restore" command? The "dump ... /home" used the nonrewinding device,
which would have left the tape positioned at the end of that backup.
The "restore" would have started there. Because using the rewinding
devicename causes it to rewind AFTER the operation, not before.
2. check your /dev nodes
#dir -l /dev/st0 /dev/nst0
should show:
crw-rw-rw- 1 root disk 9, 128 May 5 1998 /dev/nst0
crw-rw-rw- 1 root disk 9, 0 May 5 1998 /dev/st0
3. a test you could perform: after each of the dump commands, do:
#mt -f /dev/nst0 tell
this will tell you what block number the tape is at.

Ulrich,
I've installed the new modutils-2.4.2 (and all the other packages indicated in
the "Changes" document for the 2.4.2 kernel), but when I run "mkinitrd"
(version 3.0.5, and not the 2.9.1 one suggested by "Changes" since I do not
manage to find this version...) it tells me something like:
"-d option is not for linux"
and it still does not create any initrd image under /boot...
What should I do? (beside giving up :-))) )

It all depends on where you were on the tape when you started the restore.
restore can only read one "file" at a time, and those backups are in
different "files." So:
mt -f /dev/nst0 rewind
restore -if /dev/nst0
will get you /etc, while
mt -f /dev/nst0 rewind
mt -f /dev/nst0 fsf 1
restore -if /dev/nst0
will get you /home.
