Comment 13 for bug 447292

With the following change, upgrades to Lucid will adjust /etc/apparmor.d/tunables/home.d/ubuntu automatically if the administrator has not already adjusted this file via debconf. From the changelog:

apparmor (2.5~pre+bzr1362-0ubuntu2) lucid; urgency=low

  * debian/apparmor.postinst: on upgrades, prepopulate apparmor/homedirs
    if it is not preseeded. Will check /etc/passwd for UIDs >= 1000 and
    < 30000 for unique dirnames of home directories that are not /home. Fully
    resolves (LP: #447292)
