Description Sepp Rudel 2003-04-07 07:43:16 UTC
Description of problem:

After installing RH9 (and betas that preceeded it) and running

prelink -avm

causes following error during next boot:

umount: /: device is busy

If the same command is run later, no error appear.

Version-Release number of selected component (if applicable):

prelink coming with RH9.

How reproducible:


Steps to Reproduce:
1. Install RH9
2. Run prelink -avm
3. Reboot and look at the messages
    
Actual results:

umount gives errors.

Expected results:

umount goes ok.

Additional info:

I know the instructions to reproduce are PITA and it may well be that prelinking
some certain files is the cause but since I don't have a slightest clue what it
might be, I won't iterate this. However, as noted above, I've noticed this same
behaviour with RH9, and every 8.0.9x betas. Probably with RH8, too, IIRC.

Comment 1 Jakub Jelinek 2003-04-07 07:46:20 UTC
Does
telinit u
after
prelink -avm
help? Without that, /sbin/init is still using the old copy of libc and thus
the root is really busy.

Comment 2 Sepp Rudel 2003-04-07 16:40:43 UTC
But of course! telinit u solved the problem. Perhaps this could be mentioned on
the man page, there was some noise about this amongst the Debian tribe IIRC.

FWIW, I can now reproduce this naturally with:

prelink -au
reboot
prelink -avm
reboot
[etc]

Comment 3 Jakub Jelinek 2003-10-06 07:31:34 UTC
prelink 0.3.0-1 and later (ATM 0.3.0-6) should deal with it in the cron script
which does the prelinking automatically.
