Description Viraj Alankar 2000-09-07 23:12:49 EDT
Upgrading stock 6.2 glibc to:


causes a strange problem that I'm able to duplicate on similar machines. 
After doing the upgrade with rpm -Fvh, rebooting the system causes:

Unmounting file systems umount2: Device or resource busy
umount: /: device is busy

mount: / is busy
Unmounting proc file system
mount: / is busy

The system is then rebooted, and an fsck is run at next bootup. Rebooting 
again causes no problems.
Comment 1 Jakub Jelinek 2000-09-10 16:05:45 EDT
That's because init was still using the old glibc at reboot time.
Run telinit u after upgrading glibc if you want clean reboots after
glibc upgrade.
I have already coded a program which will take care of doing
telinit u on upgrades (it is tricky because of package dependencies),
it will appear in the next glibc 2.1.93+ build.
