Public bug reported:
I'm giving ubuntu-8.04-beta-server-amd64 a go on my new home server. It
installed fine and is mostly running well. Sharing files and (hopefully)
a printer via samba is the major task for the server.
I've installed SELinux (learning opportunity) and one outstanding
problem is getting cups running.
When I (re)install cupsys and cupsys-client I get the following:
The following NEW packages will be installed:
cupsys cupsys-client
0 upgraded, 2 newly installed, 0 to remove and 6 not upgraded.
Need to get 0B/1970kB of archives.
After this operation, 10.5MB of additional disk space will be used.

When I set SELinux to permissive cupsd starts and runs OK.
