"Stable" Part II: RAID confusion

The rushed release let another major problem slide in unnoticed: former users of raidtools2 with more than one RAID array suddenly have their arrays switched in unpredictable ways. The old /etc/raidtab is completely ignored by the new mdadm package, and one has the choice of either autodetecting arrays (with the /dev/md* order totally unrelated to raidtab), or not doing so -- in which case none of the arrays are brought up at all. Anyone running a RAID array will have to deal with absence or rearrangement of RAID arrays at the next reboot with zero notice, unless you happened to read all of the mdadm documentation thoroughly between upgrade and reboot and took all necessary action to check the autodetection order in advance. (The debconf information doesn't mention this at all.)
This issue is now Debian Bug #315004.
This problem entered sarge just days before release. Unlike potato and woody, there were no testing cycles this time. Thanks guys!
