Title:
  premature exit if find corrupted cache files

Status in “apparmor” package in Ubuntu:
  In Progress

Bug description:
  2.8.96~2652-0ubuntu4 did this:
    * debian/lib/apparmor/functions: don't pass costly '-n1' to xargs in
      foreach_configured_profile() when loading valid cache files. This used to
      be needed when apparmor_parser would generate different binary caches when
      compiling policy one profile at a time and all at once. That bug is long
      fixed and removing -n1 gives a significant performance improvement for
      boots with valid cache files (~65% on armhf)

  This is great except there is a parser bug that if there is a
  corrupted cache file, all further cache files fail to load. While it
  is unusual to have corrupted cache files, the damage is catastrophic
  if an early cache file is corrupt since all remaining policy fails to
  load and requires the user to manually delete the corrupted cache
  files. Fixing the premature exit will not address corrupt cache files,
  but will allow the remaining good cache files to load.

  Please see bug #1371765 on how to make cache usage more robust.
