I dont think this is strictly true. Usbmuxd must be up and running or
the internet connection does not work. I recall seeing TX timeout
messages in syslog if usbmuxd failed to start/was not running while
trying to communicate over the ipheth interface.
I'll try and sum up what I think is needed:
1. libimobiledevice supplies some sort of pairing utility, or set of
utils which can pair, unpair, and list.
2. This <idevicepair> util gets packaged in Debian in the existing
libimobiledevice-utils package.
3. The existing ipheth-utils package should be renamed to ipheth-support which:
a. supplies a udev rule;
b. depends on libimobiledevice-utils.
Does this sound sensible?
I may need some help with the udev rule... The existing ipheth udev
rule could do with some work. I have not had time to test it yet, but
I had been planning to replace it with this:
=8<==
ACTION=="add", SUBSYSTEM=="net", ENV{ID_USB_DRIVER}=="ipheth",
ATTR{idVendor}=="05ac", RUN+="ipheth-pair"
=8<==

Paul.
