I've had a call from a friend whose system wouldn't boot anymore. He has an on-board SATA controller which is active in the initramfs and several IDE controller which are only loaded once root is mounted. He has tons of stuff in /etc/crypttab, I put the IDE drives in there with UUIDs due to problems with changing drive names. Exactly one of the many LUKS devices doesn't show up in /dev/disk/by-uuid/ anymore since an update of initscripts, udev and glibc this week. The other LUKS devices are still there, exactly that one is missing. cryptsetup displays the correct UUID and the device can be unlocked fine. It's also completely reproducible, it's always the same device. I even switched him from ide drivers to libata drivers (he still had the former in rc.conf) and the result is the same. I am lost here, does someone have ideas?
