It's likely that a user might want to set multiple values for
relay_domains, transport_maps, and local_recipient_maps, and the order
is significant. This means that there's no good way to set these
across multiple NixOS modules, and they should probably all be set
together in the user's Postfix configuration.
So, rather than setting these in the Mailman module, just make the
Mailman module check that the values it needs to occur somewhere, and
advise the user on what to set if not.
This replaces all Mailman secrets with ones that are generated the
first time the service is run. This replaces the hyperkittyApiKey
option, which would lead to a secret in the world-readable store.
Even worse were the secrets hard-coded into mailman-web, which are not
just world-readable, but identical for all users!
services.mailman.hyperkittyApiKey has been removed, and so can no
longer be used to determine whether to enable Hyperkitty. In its
place, there is a new option, services.mailman.hyperkitty.enable. For
consistency, services.mailman.hyperkittyBaseUrl has been renamed to
services.mailman.hyperkitty.baseUrl.
Using a custom path in the Nix store meant that users of the module
couldn't add their own config files, which is a desirable feature. I
don't think avoiding /etc buys us anything.
The php installer creates a random one, but we bypass it, so we have
to create one ourselves.
This should be backward compatible as encryption is used for session
cookies only: users at the time of the upgrade will be logged out but
nothing more.

If the database is local, use postgres peer authentication.
Otherwise, use a password file.
Leave database initialisation to postgresql.ensure*.
Leave /var/lib/roundcube creation to systemd.
Run php upgrade script as unpriviledged user.
Supporting a path here is important because it allows e.g. fetching a
configuration from a URL. To do this and provide the configuration as
a string, IFD would be necessary. It's just written into a path
anyway.
A centralized list for these renames is not good because:
- It breaks disabledModules for modules that have a rename defined
- Adding/removing renames for a module means having to find them in the
central file
- Merge conflicts due to multiple people editing the central file
When mailman-web restarts, it removes the generated "static" directory. This
breaks a currently running httpd process, which needs a re-start, too, to
obtain a new handle for the newly generated path.
Any system uid will do, so we let the system allocate
one for us. The 'mailman' group is gone entirely since
we don't need it. Users who wish to run the 'mailman'
administration utility can do so via 'sudo':
$ sudo -u mailman mailman info
Also, simplify the syntax of our user.users entry to
rely on an attribute set rather than a list.
The `keys.target` is used to indicate whether all NixOps keys were
successfully uploaded on an unattended reboot. However this can cause
startup issues e.g. with NixOS containers (see #67265) and can block
boots even though this might not be needed (e.g. with a dovecot2
instance running that doesn't need any of the NixOps keys).
As described in the NixOps manual[1], dependencies to keys should be
defined like this now:
``` nix
{
systemd.services.myservice = {
after = [ "secret-key.service" ];
wants = [ "secret-key.service" ];
};
}
```
However I'd leave the issue open until it's discussed whether or not to
keep `keys.target` in `nixpkgs`.
