vinum root mount cannot be found
Vinum cannot read the configuration off of partitions ATM during boot since it
starts accessing (or more precisely tries to) the slices and partitions before
they are registered with devfs (before I can see things like "da0: type 0xa5,
start 63, end = 312581807, size 312581745 : OK" in dmesg which is printed by
ckeck_part() which is called by mbrinit() in sys/kern/subr_diskmbr.c).
Talked with Simon (corecode) on IRC and according to him, it seems vinuminit
needs to be run after disk probing (which currently does not).
P.S.: Also while playing around with vinum, produced the following patchset
which maybe could be useful?
1. When calling init_drive() from read_drive_label() change the static 0 with
the verbose var that is passed to read_drive_label().
2. Changed the way the drives are parsed in vinum_scandisk() and removed the
second iteration of detecting vinum partitions ... everything should be done
in the first iteration? If you provide the slice and maybe even the partitions
it should check that, otherwise it should check everything including the

It seems vinum tries to use /dev before it is available. A possible workaround
might be to do the following change to sys/dev/raid/vinum/vinumio.c:
In open_drive(), remove the conditional branch "if (rootdev)" and only leave
the content of the else branch.
This will remove dependance on /dev, and might solve the issue.
