It is an interesting thread. I don't think there was any agreement, but there
"Of course the world isn't as black as white as you paint it hence why udev will
still read files from /etc/udev/rules.d so hackers, ppl building embedded
systems and hobbyist users can override rules there."
"In fact, we should put

in the top of each udev rule. Then said man page can tell the user what
This has been done.
I don't know of any time the rules have been changed by upstream without
changing the code though. The issue of updates are far more important to
commercial distros where the users may blindly do a rpm --upgrade or similar
For LFS, it is still "Your distro, your rules" Putting what appears to be
configuration file sin /lib just tends to hide them to "protect" them from
users. Our role is to spread information on how a system is built so users can
make changes more intelligently.
I'm not opposed to adding more verbiage to the udev section to caution users
that upstream does not recommend changes.
There is another issue. If udev rules were split into an upstream location in
/lib and user modified rules in /etc, someone that wanted to make a legitimate
change would probably have to review the rules in both locations anyway.
I say keep them in /etc.
