After initramfs, you can unmount fs as usual which was mounted in initrams. But you cannot unmount root. For aufs-rooted system, please refer to the aufs manual. Particulary, (from the aufs manual) ---------------------------------------------------------------------- When your aufs is the root directory of your system, and your system tells you some of the filesystem were not unmounted cleanly, try these procedure when you shutdown your system. .nf # mount -no remount,ro / # for i in $writable_branches # do mount -no remount,ro $i # done .fi If your xino file is on a hard drive, you also need to specify `noxino' option or `xino=/your/tmpfs/xino' at remounting root directory. ---------------------------------------------------------------------- J.
