It seems that Hardy has silently introduced AppArmor and now I am unable to run mysql like I want anymore. The problem is that obviously AppArmor prevents mysql from using files that reside on a different disk.
However, because of size and backup considerations I need to have parts of mysql on various other disks!
I am desperately trying to re-create the installation I had running under Gutsy under a freshly installed Hardy and this is one of the major stumbling blocks!
I also read that there are problems with cups and AppArmor -- so instead of tinkering with it, can I just disable it entirely? I definitely dont need it, thank you very much.
