Thanks for the explanation, now I have a better idea. I was aware of
the devname and media-presence stuff, but didn't think that was
relevant since it arrived post-.34 and can be worked around using
custom rules and static nodes. That custom rules might be needed on
old kernel is already clear from the README so that's fine.
If I understand you correctly, I think the README should be reverted to say
"Requirements:
- Version 2.6.32 of the Linux kernel [...]"
The broken syscalls on pre-.34 kernels on some architectures is
already mentioned explicitly:
"- Some architectures might need a later kernel, that supports accept4(),
or need to backport the accept4() syscall wiring in the kernel."
I agree that it would be best to drop old kernels, but as long as
people would like to try I guess that's up to them.
Cheers,
Tom
