[buildd-tools-devel] Bug#686148: schroot: Does not unmount /run/shm

[Daniel Dehennin]

Package: schroot
Version: 1.6.3-1
Severity: minor

Dear Maintainer,

I noticed several “/run/shm” in my mount since a moment but did not
figure out where they came from.

I just create a new schroot and got one more, I umount all superfluous
“/run/shm” and run “schroot -c sid-amd64-sbuild” and got:

  /dev/mapper/hati-sid--amd64--sbuild--a91d556e--4f12--4e9c--9c00--b7f4ee915b59 on /var/lib/schroot/mount/sid-amd64-sbuild-a91d556e-4f12-4e9c-9c00-b7f4ee915b59 type btrfs (rw,noatime,space_cache)
  proc on /var/lib/schroot/mount/sid-amd64-sbuild-a91d556e-4f12-4e9c-9c00-b7f4ee915b59/proc type proc (rw,nosuid,nodev,noexec,relatime)
  sysfs on /var/lib/schroot/mount/sid-amd64-sbuild-a91d556e-4f12-4e9c-9c00-b7f4ee915b59/sys type sysfs (rw,nosuid,nodev,noexec,relatime)
  devpts on /var/lib/schroot/mount/sid-amd64-sbuild-a91d556e-4f12-4e9c-9c00-b7f4ee915b59/dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000)
  tmpfs on /run/shm type tmpfs (rw,relatime)
  /dev/dm-13 on /var/lib/schroot/mount/sid-amd64-sbuild-a91d556e-4f12-4e9c-9c00-b7f4ee915b59/build type btrfs (rw,nodev,noatime,space_cache)
  /dev/mapper/hati-var+cache on /var/lib/schroot/mount/sid-amd64-sbuild-a91d556e-4f12-4e9c-9c00-b7f4ee915b59/var/cache/apt/archives type ext4 (rw,noatime,data=ordered)
  

After quitting the schroot, the “/run/shm” is still here.

Regards.
