Currently, sudo doesn't work in a NixOS container running inside a Nix
build, because Nix's seccomp filter doesn't allow setuid programs. In
any case, runuser is a bit lower-overhead than sudo.
nixos/modules/config/nsswitch.nix uses `passwdArray` for both `passwd`
and `group`, but when moving this into the sss module in
edddc7c82a, it didn't get split
appropriately.
The configured mbuffer path will be called on both the source and target
system. If you use pkgs.mbuffer from the source host and the target host
does not have this exact derivation, you will get a broken pipe when
sending snapshots. This is the case when transferring to a non-NixOS
system or to a host with a different mbuffer version.
the options should not be set as we already change user with service
file, man mpd.conf says "Do not use this option if you start MPD as an
unprivileged user"
The group option actually is not documented at all anymore and probably
no longer exists.
These options get in the way of setting up confinement for the service,
as it would otherwise be pretty straightforward to setup, but even if
mpd is not root it would check the user exists within the chroot which
is more work (need to get nss working):
systemd.services.mpd = {
serviceConfig.BindPaths = [
# mpd state dir
"/var/lib/mpd"
# notify systemd service started up
"/run/systemd/notify"
];
serviceConfig.BindReadOnlyPaths = [
"/path/to/music:/var/lib/mpd/music"
];
# ProtectSystem is not compatible with confinement
serviceConfig.ProtectSystem = lib.mkForce false;
confinement = {
enable = true;
binSh = null;
mode = "chroot-only";
};
};
By default, postgres prefixes each log line with a timestamp. On NixOS
logs are written to journal anyway, so they include an external
timestamp, so the timestamp ends up being printed twice, which clutters
the log.
* Add a module option to change the log prefix.
* Set it to upstream default sans timestamp.
This reverts commits 9d0de0dc57,
27d2857a99. 'nix ping-store' is an
experimental command so it doesn't work in Nix 2.4 unless you set
'experimental-features = nix-command' in nix.conf.
This seems to have worked in 15f105d41f (5
months ago) but broke somewhere in the meantime.
The current module doesn't seem to be underdocumented and might need a
serious refactor. It requires quite some hacks to get it to work (see
https://github.com/NixOS/nixpkgs/issues/86305#issuecomment-621129942),
or how the ldap.nix test used systemd.services.openldap.preStart and
made quite some assumptions on internals.
Mic92 agreed on being added as a maintainer for the module, as he uses
it a lot and can possibly fix eventual breakages. For the most basic
startup breakages, the remaining openldap.nix test might suffice.
