Also, with a new installastion some security-settings might change asw ell (i.e. registred_globals) In general linux has a good record of backwards-compatibility as far as I've seen it over the last 7.5 years or so. But the odd thing might always happen. If you want to be sure you have to check the changelogs of the applications before installing them. As I'm a debian-user I dunno if this is possible, but always see what the upgrade is going to change install new/upgrade or posssibly remove. Specially if you are running on-the-edge unstable versions of your distro. If the server is that critical to you, install a second identical system (identical as in software) and upgrade that one first. Then check if everything works okay before upgrading the time-critical system. kind regards, Andor > Best regards > Brian > > _______________________________________________ > > Blinux-list@xxxxxxxxxx > https://www.redhat.com/mailman/listinfo/blinux-list > -- Andor Demarteau E-mail: andor@xxxxxxxxxxxx student computer science www: http://www.nl.linux.org/~andor UU based & VU guest-student jabber,icq,msn,voip: do ask ;) ----------- chairman Stichting Studiereizen Storm 2002-2004 vice-chairman USF Studentenbelangen executive committee 2002-2003 _______________________________________________ Blinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/blinux-list
