[Bug 1078425] Re: /tmp directory cleaning of folders fails if a file can't be removed

[Steve Langasek]

This seems invalid to me, then. Mountall should not be clearing
immutable bits on the filesystem. Presumably you didn't want them here
in this case, but mountall has no way to know that.

** Changed in: mountall (Ubuntu)
       Status: New => Invalid

Title:
  /tmp directory cleaning of folders fails if a file can't be removed

Status in “mountall” package in Ubuntu:
  Invalid

Bug description:
  I was surprised to discover a ton of directories in my /tmp folder.
  Digging into the issue I discovered the following in /var/log/upstart
  /mounted-tmp.log:

  find: cannot delete `./cmake-bug/cpack_test_case/tmp/378': Operation not permitted
  find: cannot delete `./cmake-bug/cpack_test_case/tmp/379': Operation not permitted
  find: cannot delete `./cmake-bug/cpack_test_case/tmp/380': Operation not permitted

  Looking in dmesg I see:

  [   89.732482] init: mounted-tmp main process (1177) terminated with
  status 1

  In /etc/init/mounted-tmp.conf we see the following:

      # Remove all old files, then all empty directories
      find . -depth -xdev $TEXPR $EXCEPT ! -type d -delete
      find . -depth -xdev $DEXPR $EXCEPT -type d -empty -delete

  So I believe that after the attempt to delete files fails the job
  exits and the directories are left behind.
