Both FC and Debian have SELinux support. AFAIK, FC has it active by default('enforcing mode') while Debian does not. On my sid system, I have have SELinux active but not in 'enforce' mode.

These are saying that this virtual filesystem is not there.
From my gut, it doesn't seem like SELinux is getting in the way. I'd see if FC has option to turn off SELinux as a kernel option or at least to turn off enforcing mode by using /selinux or chaning the policy. -- | .''`. == Debian GNU/Linux == | my web site: | | : :' : The Universal |mysite.verizon.net/kevin.mark/| | `. `' Operating System | go to counter.li.org and | | `- http://www.debian.org/ | be counted! #238656 | | my keysever: subkeys.pgp.net | my NPO: cfsg.org |
