Upstream updates roon-server frequently, and client apps (iOS, Android,
etc) will stop working with older versions of the roon-server.
We can't always keep the roon-server up to date as fast as upstream
releases, so it is often necessary for users to use an overlay or
provide their own version.
In particular the use case of running NixOS stable channel, but wanting
to use the `pkgs.roon-server` from unstable is one that I want to
support with this simple change.
Set environment variable ROON_ID_DIR to the same value as ROON_DATA_DIR
so that it knows it's the same installation after a restart.
Otherwise, each time the server process restarts, the user will need
to log in, and configure any server-local audio devices, again.
This environment variable was found in Roon's "easy installer" script:
https://help.roonlabs.com/portal/en/kb/articles/linux-install#The_Easy_Installer_Recommended
conversions were done using https://github.com/pennae/nix-doc-munge
using (probably) rev f34e145 running
nix-doc-munge nixos/**/*.nix
nix-doc-munge --import nixos/**/*.nix
the tool ensures that only changes that could affect the generated
manual *but don't* are committed, other changes require manual review
and are discarded.
the conversion procedure is simple:
- find all things that look like options, ie calls to either `mkOption`
or `lib.mkOption` that take an attrset. remember the attrset as the
option
- for all options, find a `description` attribute who's value is not a
call to `mdDoc` or `lib.mdDoc`
- textually convert the entire value of the attribute to MD with a few
simple regexes (the set from mdize-module.sh)
- if the change produced a change in the manual output, discard
- if the change kept the manual unchanged, add some text to the
description to make sure we've actually found an option. if the
manual changes this time, keep the converted description
this procedure converts 80% of nixos options to markdown. around 2000
options remain to be inspected, but most of those fail the "does not
change the manual output check": currently the MD conversion process
does not faithfully convert docbook tags like <code> and <package>, so
any option using such tags will not be converted at all.
Didn't notice this till I tried removing my custom roon user from the one I was testing with. There's not a 'groups' option for users, only group (primary group) and extraGroups. Use these.
(#68337)
DynamicUser currently breaks the backup functionality provided by roon,
as the roon server cannot write to non-canonical directories and the
recycled UIDs/GIDs would make managing permissions for the directory
impossible. On top of that, it would break the ability to manage the
local music library files (as it would not be able to delete them).
