See the added comment in all-packages.nix for a more detailed
explanation. This makes the top-level GHC different from
haskellPackages.ghc (which is build->host and used for building the
package set), but more consistent with gcc, gnat etc.
Specifically, pkgsCross.${platform}.buildPackages.ghc will now be a
cross-compiler instead of a native build->build compiler.
Since this change has a slight chance of being disruptive, add a note to
the changelog.
Update the default GNAT version from 9 to 11, as GNAT >= 11 is required
to compile the 22.* AdaCore libraries.
To allow this, we need to pick a patch from ghdl's master fixing a
compilation problem with GNAT 11.
The option `services.prometheus.environmentFile` has been removed since it was causing [issues](https://github.com/NixOS/nixpkgs/issues/126083) and Prometheus now has native support for secret files.
pam_mkhomedir should create homedirs with the same umask as the rest
of the system. Currently it creates homedirs with go+rx which makes
it readable for other non-privileged users.
Use service internal bind mounts instead of global ones.
This also moves the logs to /var/log/unifi on the host
and the run directory to /run/unifi.
Closes#61424
The new option `services.prometheus.enableReload` has been introduced
which, when enabled, causes the prometheus systemd service to reload
when its config file changes.
More specifically the following property holds: switching to a
configuration (`switch-to-configuration`) that changes the prometheus
configuration only finishes successully when prometheus has finished
loading the new configuration.
`enableReload` is `false` by default in which case the old semantics
of restarting the prometheus systemd service are in effect.
