# Attempt to automate setting up RAIDframe on >2TB disks (abs@absd.org)
#
# Intended to be run from netbsd-7 booted USB disk image
# - Creates small 'BOOT' wedge on each disk to hold /netbsd 'boot[01]'
# - Remainder of each disk put into single large wedge 'raidNcomponent[01]'
# - Creates 32K slice RAID1 device from both large wedges 'raidN'
# - Within RAID1 creates root 'raidNa', 'swap', 'home' and 'media' wedges
#
# Issues:
# - raidframe does not understand NAME=, so $RAID.conf below uses /dev/dk?
# - installboot does not understand NAME=, so uses /dev/dk?
# - requires boot partitions as cannot boot /netbsd from raid1 in wedge
