AppArmor tunables handling

Feedback jdstrand 2009-12-04: The following was discussed on irc with likewise developers (Gerald Carter). lwiauthd.conf will be adjusted to use /home/likewise-open/%D/%U. This will allow easy adjustment of /etc/apparmor.d/tunables/home, with minimal changes to likewise packaging. Upgrades should not try to perform a migration, as it is assumed that likewise administers have already adjusted tunables.

Feedback jdstrand 2010-01-07: apparmor now supports /etc/apparmor.d/tunables/home.d. AppArmor will not have the likewise-open path by default but instead likewise-open will need to ship a file in /etc/apparmor.d/tunables/home.d

Feedback jdstrand 2010-02-17: on upgrades, if the administrator has not preseeded a value for apparmor/homedirs, then postinst will look at /etc/passwd for directories to add to /etc/apparmor.d/tunables/home.d/ubuntu. getent was not used since this would be very cumbersome on large deployments. Administrators in such environments are encouraged to use the preseed.
