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

[Brian Murray]

The reason the files weren't deletable was because they have the 'i'
attribute set.

11:48:09 - flash:[/tmp] lsattr cmake-bug/cpack_test_case/tmp/378
----i----------- cmake-bug/cpack_test_case/tmp/378

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

Status in “mountall” package in Ubuntu:
  New

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.
