/var is a separate file system, and like / it's encrypted, so it might take a bit of time to activate it. Whether it's available when needed, I don't know, though the error suggests it might not be. Could systemd be launching services while some of the mounts (and the required decryption) are still to be done?
Is there some systemd way to ensure the file system is mounted before launching bind? But I'd think if /var weren't available, bind wouldn't be the only one with a problem. Ross
