Bug#753442: debootstrap: host's /run/shm gets unmounted after debootstrap run

[Daniel Reichelt <debian@nachtgeist.net>]

Package: debootstrap
Version: 1.0.48+deb7u1
Severity: critical
Justification: breaks unrelated software

Hi,

after running debootstrap the host's /run/shm tmpfs mount gets unmounted. Since
the mount point /run/shm itself is set to root:root/750, this breaks any other
package which relies on being able to write to /run/shm as non-root.

(In my case, python's multiprocessing fails miserably due to the lack of write
privileges to /run/shm, which is how I noticed this issue in the first place.)

I tried debootstrap on clean and current wheezy and jessie installations, only
wheezy was affected.

Let me know if you need any further information.

Cheers
Daniel
