These can be either an integer or a range.
Range options are necessary for `FREE_LIMIT` to take effect when used in
conjunction with `TIMELINE_LIMIT_*`.
It is currently tied to `services.avahi.enable` which might not be
desirable.
With this change it is possible to disable the service with
`services.printing.browsed.enable = false`
Factor out part of the provisioning script into a
wait-until-service-is-ready script, and put it unconditionally in
front of ExecStartPost=, so that services that depend on influxdb2 are
not started until influxdb2 responds to requests.
Fixes https://github.com/NixOS/nixpkgs/issues/317017 ("Scrutiny tries to start before influxdb has started")
When `diskImage = null`, the root fs is a tmpfs instead of
`/dev/vda`. Thus, it doesn't have to wait for virtio modules to load
before being mounted. The root fs is a dependency of shared
directories by nature of being their parent directory. Without
depending on `/dev/vda`, these shared directories may attempt to mount
without virtio modules being loaded.
In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages

There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.
