[lxc-devel] [PATCH] hooks/ubuntu-cloud-prep: add hostname to meta-data

Hi Scott,

this did manage to set the container name as hostname on first boot,
however apparently not in time for dhcp's send gethostname().  On
first boot, the parent dnsmasq couldn't resolve the hostname, but
after a reboot it could.

I don't mind applying the patch as is, but is that going to be a problem
for ubuntu-cloud users?
