The daemon is not confined by SELinux. Please help SELinux folks to create a suitable policy module. You know that we should minimize the number of programs running as initrc_t, don't you?
We're happy to help, though are not immediately able to write a selinux module ourselves. Perhaps reassign this bug to someone willing/able to do so? stap-server does a lot, so may be complicated to tie down. For example, it does all of the following unprivileged operations: - it reads files in /etc/systemtap - it talks to the local avahi daemon - it modifies files in its home directory /var/lib/stap-server (but see bug #798036) - it creates potentially large temporary files under $TMPDIR-/var/tmp - it reads files under /usr/lib/debug and /lib/modules and elsewhere - it runs make / gcc / the whole stratum of kernel-build tools/scripts - it might even be configured to make outgoing network connections to other nearby stap-servers
This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux.
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development. This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.

Milos, Is it necessary to add this capability? Or everything run fine and you just see this AVC?
