ifctl cannot be called as expected within /etc/net/identify about minibase

[arsv]

It is deliberate, for a completely unrelated reason: ifctl $iface mode foo waits for /etc/net/mode-foo $iface to finish, so it could report success or failure. Script invocations are strictly serialized, at most one script can be running for a given interface at a given time, so mode-foo $iface will not get spawned until identify exits. So you end up with a deadlock.

I think I should report EBUSY there or something.

PLEASE DON'T DO THAT. You are trying to auto-assign profiles in identify, udevd-style. The whole idea of ifmon is to avoid that. It will never work right with ifmon, it requires a different tool. identify should look like this:

https://github.com/arsv/minibase/blob/8b723a35f7099418312d0bf2f9a4f069a3214e58/src/net2/etc/net/identify

with or without the echo (probably without unless you're trying to debug it). Nothing else should be there. It's up to the user to name profiles and assign them to devices. Just leave /etc/net/mode-wifi as is, and let the user run ifctl wlan0 wifi interactively. Better yet, drop mode-wifi completely, and let wifi itself pick the device.
