Comment 1 for bug 373782

ok i reinvestigated this problem and found that this happens only when i have separate /home /usr /var /tmp partitions.

This is not a 9.04 problem, 8.04 also behaves like this.

Maybe this is not a bug, although i don't like this behavior.

I think when booting ubuntu, "kernel /boot/vmlinuz... root=..." mounts root partition read-only, and then fstab mount root partition again, and when i have separate /home /usr /var /tmp partitions it's possible to umount root partition that is mounted in fstab, then root partition becomes read-only again.

I really wish that ubuntu told me "root is busy"!
