Xen 3.0.1 with Ubuntu Dapper in DOM0

[Roberto Pereyra]

Hi

A Ubuntu developper told me that Dapper uses tmpfs in /var/run, then
it was deleted every reboot. It's not a Ubuntu bug.

Then /var/run/xentored was deleted every reboot too.

I going to port in xen-devel list this bug.

Also I rename xen-backend.rules in /etc/udev/rules.d to 92xen-backend.rules.

Please read http://polydistortion.net/monkey/archives/2006/04/21/003695.html

This is anothe xen bug (in ubuntu system)
