[Xen-users] FIX: was Re: "Exception starting xend ((2, 'No such file or directory'))" - what file?

["Dick Davies" <rasputnik@xxxxxxxxx>]

Poor form to reply to myself, I know.

Looks like Ubuntu Dapper clears out /var/run on reboot, so
I needed to add:

 mkdir -p /var/run/xenstored

to the top of the initscript to ensure dom0 comes up.

IMO it's usual to assume /var/run is transient, so it might be
an idea for xenstored to ensure it's created before trying to use it.

(We don't have a /var/lock/subsys either, but that looks less fatal :) )
