I wrote a patch, now accepted upstream, which adds the SELinux security context for each process as a new column in the process view. The patch was committed to upstream CVS HEAD on Nov 12th See this upstream bug: http://bugzilla.gnome.org/show_bug.cgi?id=150020 Once tarballs are available, you'll need to manually enable it with a "--enable-selinux" configure option, and add Requires/BuildRequires on libselinux/libselinux-devel (I'm adding this to the FC4 target tracker so it doesn't get lost)
Now building in Rawhide with SELinux support. Have a nice day :-)
