Comment (by gquintard):

 I looked at how to do it in systemd, and stumbled upon this thread :

 TL;DR : there no !ExecRestartPre/!ExecRestartCheck that would allow us to
 do it. Restart is just a stop and a start with no idea of context.

 Maybe we can tweak varnish_vcl_reload to have a dryrun/check/fake option
 that would just validate the vcl? However, that wouldn't catch errors in
 the command line, but I'm not sure anything can.
