Instead of sleep 10 is possible to use:

while ! -b /dev/sda6; do sleep 1; done
:-)


I found out and set these two variables in kernel (from 2.6.32):

# zgrep CONFIG_DEVTMPFS /proc/config.gz
CONFIG_DEVTMPFS=y
CONFIG_DEVTMPFS_MOUNT=y

>From http://cateee.net/lkddb/web-lkddb/DEVTMPFS.html :

This creates a tmpfs filesystem, and mounts it at bootup and mounts it
at /dev. The kernel driver core creates device nodes for all registered
devices in that filesystem. All device nodes are owned by root and have
the default mode of 0600. Userspace can add and delete the nodes as
needed. This is intended to simplify bootup, and make it possible to
delay the initial coldplug at bootup done by udev in userspace. It
should also provide a simpler way for rescue systems to bring up a
kernel with dynamic major/minor numbers. Meaningful symlinks,
permissions and device ownership must still be handled by userspace.


Imho, it is good idea to have it enabled. After we must remove this from
%DEV/devices

  echo "Mounting ramfs at $udev_root"
  mount -n -t ramfs none $udev_root


I updated init.d in devel-udev branch.
Please test.

Any protest?
