Description Kasper Dupont 2005-03-27 13:07:40 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1) Gecko/20031114

Description of problem:
The init script generated by mkinitrd ends with a switchroot call followed by a umount call. A succesfull call of switchroot will perform an execve system call causing the script to terminate, so the umount call will never be performed. The switchroot call leaves a few mountpoints hidden under the root, which means they are impossible to umount later during boot.

Version-Release number of selected component (if applicable):
mkinitrd-4.1.18-2

How reproducible:
Always

Steps to Reproduce:
1. grep ' /\(dev\|proc\)\? ' /proc/mounts


Actual Results:  rootfs / rootfs rw 0 0
/proc /proc proc rw,nodiratime 0 0
none /dev tmpfs rw 0 0
/dev/root / reiserfs rw 0 0
none /dev tmpfs rw 0 0
/proc /proc proc rw,nodiratime 0 0


Expected Results:  /dev/root / reiserfs rw 0 0
none /dev tmpfs rw 0 0
/proc /proc proc rw,nodiratime 0 0
