      5 can chroot inside of them.
      6 
      7 How to use it?
      8 ==============
      9 
     10 First set the `user' variable in the script to your username.
     11 
     12 sudo ./rvm create arch /home/<user>/arch-mnt
     13 
     14 This will create a volume named `arch' in the specified path.
     15 It will also backup the rootfs into a .tgz and place it in
     16 /home/<user>/.rvm.
     17 
     18 sudo ./rvm start arch /home/<user>/arch-mnt
     19 
     20 Starts the volume named `arch', at this point you can use
     21 `arch-chroot /home/<user>/arch-mnt /bin/bash' or similar to
     22 chroot into the volume.
     23 
     24 sudo ./rvm stop arch /home/<user>/arch-mnt
     25 
     26 Stops the volume named `arch'.  It will backup the rootfs
     27 into /home/<user>/.rvm/arch.tgz.
