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
