LP:876550 - apparmor blocks starting of mariadb in ubuntu ocelot (11.10)

Apparently in Ubuntu 11.10 /var/run has been moved to /run. This causes apparmor to prevent mariadb from running.

See the following related bug reports:
https://bugs.launchpad.net/ubuntu/+source/mysql-5.1/+bug/810580
https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/810270

To fix it manually, in the file:
/etc/apparmor.d/usr.sbin.mysql
I changed the lines:
/var/run/mysqld/mysqld.pid w,
/var/run/mysqld/mysqld.sock w,
to:
/

{,var/}run/mysqld/mysqld.pid w,
/{,var/}

run/mysqld/mysqld.sock w,

I think that this needs to be fixed on mariadb's end and that this is what was done for the mysql package. In any case, it works and matches the changes made for other profiles under /etc/apparmor.d
