#
##############################################################################
#
# Assumptions:
# Run this script from the hetzner rescue system
# Operating system=Linux, Architecture=64 bit, Public key=*optional*
#
# Assumes 2 or 4 identical disks at /dev/sda and /dev/sdb,sdc,sdd,sde,sdf it ignores any extra disks which are not identical
# Will make sure the raid 1 use sda and the next identical sized disk, eg. sdc if sdb is not the same siza as sda
# software raid 1 (mirror) will be setup as well as LVM and will automatically detect and set the swap size
# If 4 identical disks are detected (sda,sdb,sdc,sdd) raid 10 will be used. (mirror and striped)
#
# SWAP partition size is adjusted according to available drive space
#
# Notes:
# will automatically run the install-post.sh script
# will automatically detect and use the latest debian install image
# ext3 boot partition is always created, as per Hetzner requirements
