Sockets in /var should automatically be ordered After=var.mount, so this should in theory just work. How are you mounting /var? I assume an fstab entry would not do in your setting, so I guess you somehow generate a custom var.mount file? Please link to the code so I could have a look. > Right now, I'm thinking the only sensible solution is to forget doing it with > systemd and push the mounting of /var up into initcpio, but that's admitting > defeat. That should definitely not be necessary. -t
