# Some combinations of the tuning knobs below do not exactly make sense.
# but that's ok.
#
# If the "root_password" is non-blank, use it, else set a default.
# This can be passed to the script as an environment variable and is
# set by a shell conditional assignment.  Looks weird but it is what it is.
#
# If the root password contains a ding ($) then try to expand it.
# That will pick up things like ${name} and ${RANDOM}.
# If the root password contains more than 3 consecutive X's, pass it as
# a template to mktemp and take the result.
#
# If root_display_password = yes, display the temporary root password at exit.
# If root_store_password = yes, store it in the configuration directory
# If root_prompt_password = yes, invoke "passwd" to force the user to change
# the root password after the container is created.
# If root_expire_password = yes, you will be prompted to change the root
# password at the first login.
#
# These are conditional assignments...  The can be overridden from the
# preexisting environment variables...
#
# Make sure this is in single quotes to defer expansion to later!
# :{root_password='Root-${name}-${RANDOM}'}

# Now, it doesn't make much sense to display, store, and force change
# together.  But, we gotta test, right???

### BEGIN Bootstrap Environment Code...  Michael H. Warfield /\/\|=mhw=|\/\/

# Ok...  Heads up.  If you're reading these comments, you're either a
# template owner or someone wondering how the hell I did this (or, worse,
# someone in the future trying to maintain it).  This code is slightly
# "evil coding bastard" code with one significant hack / dirty trick
# that you would probably miss just reading the code below.  I'll mark
# it out with comments.
#
# Because of what this code does, it deserves a lot of comments so people
# can understand WHY I did it this way...
#
# Ultimate Objective - Build a Fedora container on a host system which does
# not have a (complete compatible) version of rpm and/or yum.  That basically
# means damn near any distro other than Fedora and Ubuntu (which has rpm and
# yum available).  Only requirements for this function are rsync and
# squashfs available to the kernel.  If you don't have those, why are you
# even attempting to build containers?
#
# Challenge for this function - Bootstrap a Fedora install bootstrap
# run time environment which has all the pieces to run rpm and yum and
# from which we can build targets containers even where the host system
# has no support for rpm, yum, or fedora.
#
# Steps:
#       Stage 0 - Download a Fedora LiveOS squashfs core (netinst core).
#       Stage 1 - Extract filesystem from Stage 0 and update to full rpm & yum
#       Stage 2 - Use Stage 1 to build a rootfs with python, rpm, and yum.
#
#       Stage 2 becomes our bootstrap file system which can be cached
#       and then used to build other arbitrary vesions of Fedora of a
#       given architecture.  Note that this only has to run once for
#       Fedora on a given architecture since rpm and yum can build other
#       versions.  We'll arbitrarily pick Fedora 20 to build this.  This
#       will need to change as time goes on.

# Programmers Note...  A future fall back may be to download the netinst
#       iso image instead of the LiveOS squasfs image and work from that.
#       That may be more general but will introduce another substep
#       (mounting the iso) to the stage0 setup.

# This system is designed to be as autonomous as possible so all whitelists
# and controls are self-contained.

# Initial testing - Whitelist nobody.  Build for everybody...
# Initial deployment - Whitelist Fedora.
# Long term - Whitelist Fedora, Debian, Ubuntu, CentOs, Scientific, and NST.

# List of distros which do not (should not) need a bootstrap (but we will test
# for rpm and yum none the less...  OS SHOULD be taken from CPE values but
