A new and simpler way to upgrade EON ZFS storage

There is a new and simple way to upgrade your current EON ZFS storage to the newest version. I've added a tool, transporter.sh which allows you to backup, upgrade or restore(NOTE: restore only works if you have a backed-up version) your EON ZFS storage version. Here is a usage output:

transporter.sh 
usage: transporter.sh -i /path/eon.iso -b /path/backup -d /mnt/eon0
transporter.sh -i /tmp/eon-0.593-122-64-smb.iso -d /mnt/eon0
transporter.sh -i /tmp/eon-0.593-122-64-smb.iso -b /pool/backup -d /mnt/eon0
transporter.sh -r /pool/backup/0.59.3 -d /mnt/eon0

-i path to the source ISO
-b path to the backup destination [optional]
-d path to the upgrade destination
-r path to the restore source [optional]

Here's an example run without backup options. It is always wise to have a backup. I cannot stress this enough. There is no backup in this example because I have a previous backup in /abyss/eonback/0.593.

transporter.sh -i /tmp/eon.iso -d /mnt/eon0
OK: lofiadm -a /tmp/eon.iso /dev/lofi/1
OK: mount -F hsfs /dev/lofi/1 /tmp/upgrade
removing /mnt/eon0/boot
copying /tmp/upgrade -> /mnt/eon0
