Package: udev
Version: 146-3
Severity: critical

G'day.

I recently upgraded to the latest udev, help up by the fact that I use
MD software RAID and needed to wait for the mdadm package to catch up.

On reboot my system broke: it could no longer locate the root device.

Having checked by poking around in the initramfs environment this is
because of this change (as far as I can tell):

udev (146-2) experimental; urgency=medium
[...]
  * Copy in the initramfs only the rules files which are needed to mount
    the root.

Unfortunately, the rules that create the symlinks from
/dev/disk/by-id/md-uuid-* to the /dev/md* devices were *not* considered
necessary for mounting the root.

On the other hand, they *were* necessary in my boot stack, which is:

    md RAID10 => dm_crpyt => lvm => root

Specifically, I used the 'by-id' name for the MD device in
/etc/crypttab, which was no longer created, so the second stage failed.


I appreciate the desire to boot faster, but it is a very, very
significant change to stop creating those device names in the initramfs
since it can break, and make *very* difficult to recover, a previously
working system that used them.


I can supply whatever extra detail is required; I have verified that,
indeed, it is specifically that only the ATA devices, and none of the
soft "logical" devices, that get by-id links in the initramfs already.

Regards,
        Daniel
