Hi all,

when I switched to Chimaera, one of the difficulties was an /etc/selinux directory left over since several years ago. After boot with the new system, X didn't want to start. It said something about selinux, so I found the leftover and startx worked again.

Now I checked what selinux packages are installed, and find libselinux1. If i try to remove it, I get errors like:

:~# apt-get purge libselinux1

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

Running `apt-cache rdepends libselinux1` reports lots of essential packages. Is that correct?

Perhaps all what they need is to call is_selinux_enabled() from libselinux.so.1. Does it make sense?

Did we have it on Beowulf?
