If it's just DNS, then yes. But I have a few more dependencies which I'd like to resolve, like NFS-shares. One way I've been thinking of is to delay startup of dependent domU's till the "login" text appears in the /var/log/xen-consoles/* logfile for the domU. I configured different stage-init-scripts per domain to make it easier and have the reverse action (shutting down) correct. For now, boot-up still requires manual work. -- Joost _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
