This sounds like a process with a very high entertainment value. :-)
I know, it's not like I haven't done that few times =D
Unfortunately, I have a FreeBSD installation already, so... spoiler
alert, test results are below.

^^^^^^
should be 'loopback_name'.
🤦 so few rounds of refactoring will not be hidden under the covers.
OK, OK, I admit I didn't write it in one go =D
After that I have networkxml2conftest runs smoothly for me.
Great!

Out of curiosity, can we use virStringReplace() here? I still have this
8-0 We have that? I feel like I should've known... Or at least
should've tried looking for it.
working with the following change (along with the loname fix):
Perfect. ACK to your version if you're OK with it as well (the only
ACKs I've found in this mail are in the 'LOOPBACK' placeholder ;)), then
feel free to push it since you have the working commit handy.
