Subject: Do not throw warnings when /tmp/custom_mounts.list does not exist.
X-Git-Tag: debian/4.0_alpha20-1~1
X-Git-Url: http://git.grml.org/?a=commitdiff_plain;h=28ca8298a10702e391e420975205a98450d4cf7d;hp=28ca8298a10702e391e420975205a98450d4cf7d;p=live-boot-grml.git

Do not throw warnings when /tmp/custom_mounts.list does not exist.

When no device for an overlay can be found, /tmp/custom_mounts.list
won't be created and will produce warnings while booting:

  sort: /tmp/custom_mounts.list: No such file or directory
  rm: can't remove '/tmp/custom_mounts.list': No such file or directory

Properly handle this case by calling rm with the -f option and calling
sort only when the file exists.
