[Pkg-sysvinit-devel] Bug#704108: umountfs: cannot unmount unusual bind mounts

[Askar Safin]

Package: initscripts
Version: 2.88dsf-41
Severity: normal

Steps to reproduce:

mkdir /mytmp
mount -t tmpfs tmpfs /mytmp
mkdir /mytmp/root
mount --bind / /mytmp/root
reboot

What I see:
umountfs fails

What I should see:
umountfs should not fail. It should successfully umount /mytmp/root, and then /mytmp

Cause of bug (I think):
In the top of the umountfs script we unmount tmpfses. But we should also unmount their dependencies
