Hi. I'm fairly new with CentOS but have been using version 4.2 with great satisfaction (Thank you!). I've been using repos such as Dag and Dries successfully to keep my packages up to date. (I've seen many posts which allow me to believe that these repos won't change CentOS compatibility to RHEL4 or to migrate it another distro for that matter!) My question applies to the ATRpms repo (which has el4 rpms). Can I safely use this repo to "yum update" my system? When I added the repo to the yum repos (and to the up2date repos as well), I noticed more than 100 packages to be updated (some seem to be system packages like alsa-lib, autoconf, glib2, etc.) Can I update with this repo and maintain same basic system and functionality? Thanks for your answers. Sincerely Jose
