Hello Tino, finally I think I found a solution: I would crate a second systemd unit template coping [email protected] to [email protected] and then I'll remove from the latter the BindsTo= and After= lines, replacing them with a dependency on the iaxmodem.service unit.
This means that "real" devices, the one managed by udev, like ttyS0 or ttyUSB3 will get a normal [email protected] unit that depends on the device; while the "virtual" device like ttyIAX0 will only get a dependency on the iaxmodem service and will be coupled with a systemd path unit that watches the IAX device name. Bye, Giuseppe
