starting with an empty /dev

["Marco d'Itri" <md@Linux.IT>]

IIRC initramfs already contains these devices, but anyway it's important
to remember that if they are removed everything will break.
Should we start thinking about how udev could be used in the real world?

Maybe you dont care but I have installed udev and it is working for me great.
But there were some problems.

I have found that devices:
/dev/null,
/dev/console

are needed befode /etc/init.d/udev starts (/etc/rcS.d/S37udev) so I twisted
the init script not to remove those file during shutdown, and to create it
during booting only if needed.

I didnt know where should I send this thing (maybe this is only my problem) but
I use your debs so I am sending it to you.

Bye
