# We want to make sure that openssh-server is not installed by default.
# Due to ssh-import-id being part of the server-minimal task, and the fact
# task headers can't be updated post-release, we need to do clean-up
# of the layers to ensure openssh-server is not part of a layer that curtin
# will copy to the target.
#
# In practice this means ubuntu-server-minimal (minimal) and
# ubuntu-server-minimal.ubuntu-server (full) need to be cleaned up.
# ubuntu-server-minimal.ubuntu-server.installer (live) _needs_ these
# packages so Subiquity can utilize them, so don't modify that layer.
