Either you don't care about interface names and you disable the udev rules for wireless interfaces (iwd default config), or you say that naming is more important than speed to you so you mask the configuration shipped by iwd and then make iwd wait for udev rules to be applied.Sure. But then again it's exactly the question I have above: what do I wait "on" in order to ensure interface names have settled?
I guess you could write a small shell script which loops until the interface name has been renamed and order iwd after it.
I've not seen any other practically workable options available right now without having to do fundamental changes to existing policies in other software - not udev or iwd (eg. linux, et.al.)I'd like, ideally, to keep stable interface names. I'm not sure if this is intended, but so far after masking 80-iwd and removing "keep" from the NamePolicy it seems that udev is always able to rename the interface across reboots. It might entirely be because iwd started to operate on the original device name, but didn't have time to bring it up before the rename happens I guess.
