Below are the  How to and outstanding problem to share with you :

Debian upgrade

I upgraded a -stable box to -testing. Mostly went well, but in one or two cases ... well, not so well.

Random starting of daemons: Yes, this has been the case in Debian for a long time, however, it gets worse when a dependency pulls in a new daemon and restarts *that*, and suddenly you are left with a nice, blank page. Actually, it didn't do that, but gave you a directory listing of what it *thinks* is the root www directory. You're left wondering, why? (the culprit, by the way, is Apache2)

Stuff that does not work out of the box: I could not get Exim4 and mailman to play nicely. First: Exim4 does not handle pipe transport out of the box, so none of the aliases stuck into /etc/aliases for mailman actually work until you uncomment it out. Mailman does not play nicely because Exim starts with Debian-exim group, and mailman will whine because that's not what the default gid is configured to at compile-time. The README files does contain some information on how to make it work .... but it was more like "Oh, just enable some random crap in your configuration file to make it work" ... hmm, nice work, considering the popularity of mailman as a mailing list software and exim as a MTA.

真人真事:CentOS apache test page 差點驚動 FBI (news by CentOS)

某鎮政府去信centos, 說他們的website給centos的人hack了.
而政府發言人所看到的, 是centos3 apache的test page.
並威脅CentOS開發人員若在12小時內不修理好, 就找FBI.
