yes it's udev-mount:

        if ! grep -qs devtmpfs /proc/filesystems; then
                eerror "CONFIG_DEVTMPFS=y is required in your kernel
        configuration" eerror "for this version of udev to run
        successfully." eerror "This requires immediate attention."
                if ! mountinfo -q /dev; then
                        mount -n -t tmpfs dev /dev
                        busybox mdev -s
                        mkdir /dev/pts
                fi


I don't see any good reason whatsoever to add /dev to fstab, unless you
want to change the default mount options for some reason

:-)

I seem to have lost my virtual consoles recently, courtesy of
udev-197 :-(

Haven't figured out why yet, I suppose I'll have to read all those
noisy udev threads again
