From 816614bd62bcdb0b72b48a55d9a5a8ffb76ce2ea Mon Sep 17 00:00:00 2001 From: tv Date: Wed, 14 Dec 2022 15:44:08 +0100 Subject: [PATCH] nixos/exim: allow using service credentials By settings User= to the actual Exim user, systemd will ensure that the credentials directory will have the correct ownership, allowing users to utilize LoadCredential=. Exim still gets started as root (and drops privileges) to preserve the previous behavior. --- nixos/modules/services/mail/exim.nix | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/nixos/modules/services/mail/exim.nix b/nixos/modules/services/mail/exim.nix index cd0da4fc5098..a9504acee351 100644 --- a/nixos/modules/services/mail/exim.nix +++ b/nixos/modules/services/mail/exim.nix @@ -116,8 +116,9 @@ in wantedBy = [ "multi-user.target" ]; restartTriggers = [ config.environment.etc."exim.conf".source ]; serviceConfig = { - ExecStart = "${cfg.package}/bin/exim -bdf -q${cfg.queueRunnerInterval}"; - ExecReload = "${coreutils}/bin/kill -HUP $MAINPID"; + ExecStart = "+${cfg.package}/bin/exim -bdf -q${cfg.queueRunnerInterval}"; + ExecReload = "+${coreutils}/bin/kill -HUP $MAINPID"; + User = cfg.user; }; preStart = '' if ! test -d ${cfg.spoolDir}; then
