I have recently updated my rawhide box with 2.6.10-1.1088_FC4.
On boot it issues messages along the lines:
failed exec /sbin/udevstart
mount: cannot create device root
This is not verbatim and there are additional lines. I have attempted to
retrieve the messages with dmesg and examined the contents of
/var/log/messages.
If someone could tell me how to collect these messages I would submit a bug.
