This allows capping the total amount of memory that will be used for
zram-swap, in addition to the percentage-based calculation, which is
useful when blanket-applying a configuration to many machines.
This is based off the strategy used by Fedora for their rollout of
zram-swap-by-default in Fedora 33
(https://fedoraproject.org/wiki/Changes/SwapOnZRAM), which caps the
maximum amount of memory used for zram at 4GiB.
In future it might be good to port this to the systemd zram-generator,
instead of using this separate infrastructure.
The `--no-build-output` flag that is added by default is only valid
for the old cli, which is not used when flakes are used.

This resolves issue #101963.
When the service is started and no interface is ready yet, wpa_supplicant
is being exec'd with no `-i` flags, thus failing. Once the interfaces
are ready, the udev rule would fire but wouldn't restart the unit because
it wasn't currently running (see systemctl(1) try-restart).
The solution is to exit (with a clear error message) but always restart
wpa_supplicant when the interfaces are modified.
This release replaces the libpulseaudio shim with a pipewire module that acts as a fake pulseaudio server along with a systemd service that loads that module on demand.
The metadata fetcher scripts run each time an instance starts, and it
is not safe to assume that responses from the instance metadata
service (IMDS) will be as they were on first boot.
Example: an EC2 instance can have its user data changed while
the instance is stopped. When the instance is restarted, we want to
see the new user data applied.
The old slapd.conf is deprecated. Replace with slapd.d, and use this
opportunity to write some structured settings.
Incidentally, this fixes the fact that openldap is reported up before
any checks have completed, by using forking mode.
According to Freenode's ##AWS, the metadata server can sometimes
take a few moments to get its shoes on, and the very first boot
of a machine can see failed requests for a few moments.
