As part of Project:Protogenoi [1], I am planning to replace root with a united filesystem using aufs. The layers will be:
Top: /dev/xvda3 (Xen/XenServer Virtual Disk device) Bottom: /.root.sqfs The aim would be to generate the smallest .xva (XenServer Virtual Appliance) possible. To achieve this, the 'physical root' at /dev/sda3 will be emptied as empty as possible, except for /etc and /dev. AFAIK, there are files that *must* still exist for this strategy to succeed. However, this post from f.g.o [2] said that those files aren't necessary. So, I should do the following sequence in /etc/fstab : 1. Mount /dev/xvda3 as / 2. Mount /.root.sqfs as / 3. Mount aufs, uniting /dev/xvda3 and /.root.sqfs as / 4. Mount everything else Am I getting this right?
