Upgraded all my machines to MDK 10.0 final. Slick.
It's a pretty good distro, which only misses out on a couple of points: urpmi is a bitch - configuring is not easy (even with the many sites dedicated to helping you); downloading large hdlist.cz files is a pain on a modem; seems to like having local CD copies available (err, my machines span 2 sites); updates aren't available all the time - perhaps this is part of MDK's general "subscribers get early access model" (et sim. phpnuke) which is silly and annoying.
My only other comment was on a personal stupidity moment. Overclocked, my IDE bus is not 100% reliable (with CDs mainly), so upgrading was a dumb thing to do: I wasn left with large amounts of /usr/bin /usr/lib /usr/X11R6/[bin,lib] and etc/pam.d bollocksed (ordinary files replaced by files which contained random data).
Luckily rpm still worked fine so (after dropping back to 133/33 and) a few lines of bash created some 'rpm -Uvh --force --replacepkgs' goodness that sorted it all, but I still felt a bit foolish.
You live and learn ;-)
