After a reboot the /var/run/sphinxsearch/ dir is removed and not created again, so sphinx won't work if users don't use the default service.

My understanding is that with the adoption of systemd temporary files and dirs should be created using config files in /etc/tmpfiles.d, /run/tmpfiles.d, or /usr/lib/tmpfiles.d.

I understand that the default service script is creating the dir but in my case I don't use the default service because I have other custom config files, so I start sphinx like this for example:

#/usr/bin/searchd -c /etc/sphinxsearch/dev.sphinx.conf

If I create the config file and reboot it works as expected:

#cat /usr/lib/tmpfiles.d/sphinx.conf
#Type Path Mode UID GID Age Argument
