Actually /etc is mounted in tmpfs so not persistent: cat /proc/mounts |grep etc none /etc tmpfs rw,rootcontext=system_u:object_r:var_lib_t:s0,seclabel,relatime 0 0 So if you want to change things you have to change it in "/config/etc/" >> the answer is yes actually. if you want a host you can change, use plain >> fedora/rhel/centos as the host. >> Fabian can reply to the rest. You can just as easily do a "mount -o rw,remount /" to edit things if you want but you have to do this on every node and again after upgrading to a newer version of node. I see it's there in the wiki: http://www.ovirt.org/Node_Troubleshooting#Making_changes_on_the_host Kind regards, Jorick Astrego Netbulae B.V.
