Yes, if I remember correctly, systemd kills all leftover ExecStartPre processes before starting the main daemon. (SIGTERM first, though.) It's intentional – ExecStartPre isn't the right place for long-running processes. Isn't there already an ifup.service or ifup@.service that VDSM could depend on? [Requires=, After=, etc.] If not, could you write one (e.g. vdsm-ifup) and *then* make VDSM depend on it? -- Mantas Mikulėnas <graw...@gmail.com>
