I debugged it by writing "set -x" and see what is executed over RS323 and
also looking at the output of "mount".

Eventually, it seems that the delay was caused by the RAMFS not booing
mounted on /dev/ which means that udev was writing real files (about 200)
over my NFS share to my real limux machine. That *is* kinda slow....

Adding the following lines fixed it (note that this mount point is not
available is fstab!):

      grep -q "^udev $udev_root" /proc/mounts || mount -t ramfs udev
$udev_root || exit 1
