Copy root filesystem to logical volume
Run the script 4.copy_root_to_mirror.sh from a root shell.
Now the entire root filesystem (/) except for mounted sub-filesystems
are copied to the logical volume root in volume group all_disks:
available as mountable device /dev/all_disks/root.
This script should be run from single-user-mode (first issue command init 1,
choose drop into a shell, then run this script, and continue booting).
If you are the only user,
and don't mind an error messages about .gvfs files,
then you may run the script without going to single user mode first.
