I'm sure you've seen this before:
You need to slightly tweak the default installation of a major daemon - let's say you're running a big MySQL database and you need to put it on a different filesystem, mounted (for example) as /db So you move /var/lib/mysql to /db/mysql (and preserve all the file attributes, including SELinux), change /etc/my.cnf accordingly, start mysqld - and it doesn't work. It turns out you need to tweak SELinux - test the daemon, run audit2allow on the audit log, tweak the policy, test again, repeat until it works.
I did this many times, but it strikes me as an inefficient process. Sure, you only do it once per install, but still.
I wish there was a simple way to tell SELinux "I moved the MySQL datadir (or the Squid cache dir, or the Cyrus-IMAPd spool) to this new location, but everything else stays the same, please stop bugging me."
Any ideas?
