# We have some out-of-tree of binary dependencies expressed below:
#
#  * vhd-util is required to create .vhd images, mostly used in
#    Rackspace.  For full details see:
#      https://docs.openstack.org/diskimage-builder/latest/developer/vhd_creation.html
#
#  * debootstrap unmounts /proc in the container causing havoc when
#    using -minimal elements on debuntu.  Two unmerged fixes are in the bullseye version:
#      https://salsa.debian.org/installer-team/debootstrap/-/merge_requests/26
#      https://salsa.debian.org/installer-team/debootstrap/-/merge_requests/27
#    are at least required.  We also need a later version to support jammy.  We
#    grab from unstable for this reason.

# Podman install mainly for the "containerfile" elements of dib that
# build images from extracts of upstream containers.
# --install-recommends is important for getting some reccommends like
# slirp4netns and uidmap that help with non-root usage -- by default
# our base container sets no-reccomends in apt config to keep package
# sizes down.
#
# Podman defaults to trying to use systemd to do cgroup things (insert
# hand-wavy motion) but it's not in the container; override to use
# cgroupfs manager.  Also disable trying to send logs to the journal.
