[Grml] /dev, udev and backup

Hi,

Do I need to backup the /dev directory when backing up my root fs?

FYI, I thought udev would populate it on boot up so I didn't backup the /dev directory. However, I got

Warning: unable to open initial console

and the boot froze.

Going through all the possible reasons in http://kerneltrap.org/node/2205 did I realize that my /dev directory should be backed up & populated.

Please comment. Thanks.
