# for GCE hosts. This flag prevents "google-compute-engine" from being a
# default dependency which is undesirable because this package is
#
#   1) available only on GNU/Linux (requires `systemd` in particular)
#   2) intended only for GCE guests (and is useless elsewhere)
#   3) used by `google-cloud-sdk` only on GCE guests
