The above is what I expected to see, which is why I proposed it for dropping
from the seed. I expect systemd to handle the core acpi events (shutdown,
suspend) directly, with no need for acpid; so acpid is only needed if you
have other custom ACPI event handlers. If you have custom ACPI event
handlers on your server, you can install the acpid package as needed; but it
is no longer part of our platform and should not be installed by default.

(It is separately still being included by default in the desktop seed
because it is a dependency of acpi-support, which ships a handful of event
handlers that had never been ported elsewhere; it is worth revisiting
whether these are now handled elsewhere or if they should be dropped as
obsolete, but in any case that should not stop us from dropping acpid from
the server seed.)
