Previously this module created both /var/db/nscd and /run/nscd using shell commands in a preStart script. Note that both of these paths are hard-coded in the nscd source. (Well, the latter is actually /var/run/nscd but /var/run is a symlink to /run so it works out the same.) /var/db/nscd is only used if the nscd.conf "persistent" option is turned on for one or more databases, which it is not in our default config file. I'm not even sure persistent mode can work under systemd, since `nscd --shutdown` is not synchronous so systemd will always unceremoniously kill nscd without reliably giving it time to mark the databases as unused. Nonetheless, if someone wants to use that option, they can ensure the directory exists using systemd.tmpfiles.rules. systemd can create /run/nscd for us with the RuntimeDirectory directive, with the added benefit of causing systemd to delete the directory on service stop or restart. The default value of RuntimeDirectoryMode is 755, the same as the mode which this module was using before. I don't think the `rm -f /run/nscd/nscd.pid` was necessary after NixOS switched to systemd and used its PIDFile directive, because systemd deletes the specified file after the service stops, and because the file can't persist across reboots since /run is a tmpfs. Even if the file still exists when nscd starts, it's only a problem if the pid it contains has been reused by another process, which is unlikely. Anyway, this change makes that deletion even less necessary, because now systemd deletes the entire /run/nscd directory when the service stops. |
