Wolfram, is there a better way to get something stable for user space to
interact with? Is there maybe a way to do this with aliases or something?
Setting up an ad-hoc scheme for forcing the adapter IDs feels a bit outdated.

Yeah, it feels rightfully outdated IMO. Bringing such policy into the
kernel is frowned upon. I think the proper way is a udev rule to act on
the newly created I2C adapter. This even could provide a really stable
symlink for userspace to consume. The above scheme is only stable per
"block" but inside the block, there is still randomness. Or?

Right, that makes sense. Thanks! Vadim, is there any reason to not solve this
with udev? Doing that with care could perhaps provide stable names even if
you swap slots?

Cheers,
Peter
