Indeed, this is the root of the problem.  Your /home partition isn't
labeled since it was carried over from an earlier installation, so it
gets the default_t type.  Personally, I would have done:

restorecon -v -R /home

I don't think you would have seen this particular issue if you'd done a
fresh installation.

No, no, that's entirely the wrong approach.  You were running into
problems with Apache.  It's very easy to turn off enforcement *just* for
Apache.  That's one of the great things about SELinux, is that it's very
flexible.  See this question in the FAQ:


I fully expect that a number of people will turn off SELinux enforcement
for Apache; by far it is the most configurable and complex daemon we
ship, and writing policy for what some people do with it could be
difficult.  But you don't want to give up protection for portmap, bind,

I also have written a specific Apache-SELinux guide that is pending
review.  I hope to get it published on fedora.redhat.com soon.
Hopefully enough people reading it and keeping enforcement for Apache on
will help stop the next Slapper worm.
