[LAD] (Somewhat OT) Advice needed on distro choice

Hello all, A number of system here, including the ones at the Casa del Suono are to be upgraded in the coming weeks. At the moment they all run Fedora 8, so the first choice would be to go for Fedora 11. But: * None of them will run Gnome or KDE. * Most will be headless anyaway. * I want access/privilege control to be based on user and group ID and nothing else. Privileges will never depend on the user having a local login or desktop session. * I'm prepared to have to spend some time configuring udev, pam, /etc/fstab etc. etc. etc. * What I certainly *do not want* is some parallel access control system that would interfere with the above, or that could modify/bypass/enhance in any way what has been configured there. * I'm *not* really prepared to have to waste any time reconfiguring the Kit family. Consequently I don't want to see any of them. So what distro should I go for ? Having to spend weeks compiling everything from source is not an option. Anyone able to point in the right direction will receive my eternal gratitude which could be expressed in quantities of fine Italian food and drinks if the occasion arises. Ciao, -- FA Io lo dico sempre: l'Italia è troppo stretta e lunga.
