-# REPARTITION: we try to reuse partitions/filesystems to install a new
-# os into a multi-os system, if we see some basic hueristics, like the
-# right amount of them. This overrides that.
-#
-# REROOTFS: Don't reuse the root filesystem, even if we normally would
-#
-# NOWIPE: use existing subvolumes if they exist
-#
-# PARTITION_PROMPT: If we don't see partitions to reuuse, prompt
-# to make sure we really want to repartition and use a completely
-# fresh install. I use this in case our repartition check has
-# a bug in it, or I accidentally set REPARTITION.
-#
-# ROTATIONAL: in a system with ssd and hdd, install to the hdd
-# instead of the default ssd.
-#
-# RAID0: Use raid 0 even if there are >= 4 disks with boot partitions.
