Description Ivan Zakharyaschev 2008-12-21 00:03:24 MSK
I installed 4.1 Desktop from the DVD. I followed the defaults in the installer (except for manually making the partitions).

It doesn't start anything on boot now.

The last things that can be seen on the screen (for example, when booting "failsafe") are:

INIT: version 2.86 booting

Enter runlevel: 3
INIT: Entering runlevel: 3
INIT: no more processes left in this runlevel

(That's me who entered 3 in the second non-empty line.)

/root/.install.log

The install log extracted via LiveCD. (I don't care about the plaintext passwords there, I'll change them.)

It was readonly initially in the "single" mode.

Comment 7 Ivan Zakharyaschev 2008-12-21 04:46:07 MSK
https://bugzilla.altlinux.org/show_bug.cgi?id=17972 looks similar.
Comment 8 Ivan Zakharyaschev 2008-12-21 16:34:16 MSK
Is it because of XFS?
Comment 9 Ivan Zakharyaschev 2008-12-23 02:07:46 MSK
Viewed superficially, it's SysVinit-2.86-alt2 who doesn't do what it is supposed to do.
Comment 10 Dmitry V. Levin 2008-12-23 02:15:28 MSK
/sbin/init has nothing to do with FS type.
Either initrd.img is not functional or smth odd happened.
Comment 11 Ivan Zakharyaschev 2008-12-23 03:50:49 MSK
/etc/inittab is empty. Ha-ha, this could be the famous misfeature of XFS, which zeroes files left open. (It could be left open by the installer? Perhaps. By another init? Probably not, init doesn't have to open it for writing...)

This is an installer bug.

Here is some information from stat that could give hints about the stage of the installation at which this file has been touched:

Comment 14 Ivan Zakharyaschev 2008-12-23 04:45:58 MSK
The stat of /etc/inittab indicates it was "modified" at the last moment of the installation:

# find /mnt/sda5/ -newer /mnt/sda5/etc/inittab
/mnt/sda5/var/lib/rpm
/mnt/sda5/var/run
/mnt/sda5/etc
/mnt/sda5/etc/mtab
/mnt/sda5/root
/mnt/sda5/root/tmp
/mnt/sda5/root/dmesg.out
/mnt/sda5/root/mount.out
/mnt/sda5/root/df.out
/mnt/sda5/root/.bash_history
/mnt/sda5/root/.lesshst

Comment 15 Ivan Zakharyaschev 2008-12-24 19:24:20 MSK
> Installer does not unmount root fs

Yes, it writes in the end:

Remains mounted: /destination
Remains mounted: /destination/home

I performed the installation once again: on XFS, but with slightly different partition layouts and with more packages.

This time zeroing of /etc/inittab didn't happen.
Comment 16 Michael Shigorin 2014-11-05 20:41:38 MSK
В 4.1/branch исправления не будут вноситься уже технически (заглушена очередь на сборку), поэтому прошу ошибки, актуальные для sisyphus/p7/t7, перевесить на текущие ветки или сизиф.
