Rebuild /dev accidentally deleted

Question

How to rebuild /dev on an ubuntu lucid where all files in /dev were accidentally deleted ?

MAKEDEV std and MAKEDEV pty aren't enough, which isn't surprising on a system under udev.

I haven't reboot yet because I fear to loose access to my system.

Answer 1

I believe the contents of /dev are automatically rebuilt when you reboot.

To quote someone else:

When you start the system, the "udev" facility examines the hardware configuration (according to established rules) and dynamically creates the entries in /dev.

Answer 2

/dev is on a RAM disk so it gets destroyed and recreated on any reboot
