If the post install script finds VMELILO on the system (/sbin/vmelilo),
it checks to see if a configuration file (/etc/vmelilo.conf) already
exists. If not, it creates a boilerplate VMELILO configuration file
that will work with the image just installed, as follows.

It looks into /etc/fstab, looking for the device that the root (/)
directory is on, ignoring swap, NFS and proc file systems it assumes
that the drive that the root device is on should be where VMELILO
installs the boot sector (this is not good for all installations, but
it gives a starting point) and inserts lines like (assuming the root
directory is on /dev/sda2):
----------------------------------------------------------------------
boot      = /dev/sda
root      = /dev/sda2
----------------------------------------------------------------------

and then appends the following:
----------------------------------------------------------------------
default   = Linux
delay     = 2

[boot]
label     = Linux
image     = /vmlinuz
read-only
----------------------------------------------------------------------
