# assign classes to hosts based on their hostname

# NOTE:
# 51-multi-boot should have something like this
# for transient host configs which are not saved in
# git (and make it executable):

# if [[ ! -e /a/bin/fai/fai-wrapper ]]; then
#     case $HOSTNAME in
#     frodo) echo STABLE ;;
#     esac
# fi


# do not use this if a menu will be presented
[ "$flag_menu" ] && exit 0


# For multi-boot system.
# Check that we aren't in a pxe boot environment.
# There is probably a better way to do this.
# We check the reverse condition in 51-multi-boot,
# and set what os we are installing, but don't check it
# into git since it changes regularly. Each host needs
# to have a class of either DEBIAN + (STABLE or STRETCH64 or STABLE_BOOTSTRAP),
# or UBUNTU + XENIAL64.
#
# Other notable classes:
#
# 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.
#
# 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 partititions.
#
# It's shell looks like this:
# if [[ ! -e /a/bin/fai/fai-wrapper ]]; then
#     case $HOSTNAME in
#         tp) DEBIAN STABLE ;;
#         # add more multi-boot hostnames here
#     esac
# fi
