# NOTE(JayF): Upstream dep list in human-readable format:

# NOTE(JayF): Blockers for these are not ideal, however all three
#             of these packages implement the same service on dbus
#             and have conflicting files as a result. Long-term
#             there likely needs to be a better solution. See
#             https://bugs.gentoo.org/967823.
