# It's a little insane this installer cannot be run headless, perhaps for license

disable partman from debian preseed
View disable-partman-hack_preseed.cfg
# Thanks to http://ubuntuforums.org/showthread.php?t=1411273 for inspiration..
# But what a disgusting nasty hack! This prevents partman from running (and
# mounts /target, creates /target/etc/fstab). d-i just can't cope with
# installation to partitionless block device... which is disappointing,
# because partitions are pointless for pvlinux guests.
#
# The hack works by ... wait for it... spawning a little while/sleep 1 script,
# waits for the partman-base.postinst file to appear (the preseed/earl_command
# hook is too early, and the partman/early_command is too late). Once it
# appears we replace this with a bit more script which does what we wanted

# `prepare_dir_tarball some_dir`

# Given a directory name in the pwd (with NO trailing slash), create or update
# `some_dir.tar.gz` only if the contents of the tarball would actually change.
#
# Although Dockerfiles allow you to ADD a directory, this isn't cacheable.
# Instead, maintain a tarball which allows you to ADD a host directory as a file
# which *is* cacheable. I.E.:
