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.
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.
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]
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.
