No, I stated that rules which are not supposed to be edited should move to /lib/udev/rules.d/, including the stuff from all the other packages. > They ship with udev and are replaced only by udev. The udev owned rules are only replaced by udev, sure. But other packages use that too. /etc/udev/rules.d/ should be only for on-demand, or user created rules. Just think of a fully converted system, where you could do "rm /etc/udev/rules.d/*" if you want to start from scratch. > Hardly.

They are "private to a package" in a sense that the user/admin has not to touch it, and they get replaced on package update without any warning. > It seems like you thought I wrote "/lib/udev/rules.d" instead of > "/lib/udev".

Kay? Absolutely, /lib/udev/ _is_ a public interface, and the only place supported by udev. /lib64/udev/ is a broken installation. The source code even hard-codes that path in some cases. It is intentionally not configurable. LSB suggests directories like this, it is well defined, that part of LSB makes a lot of sense, and we use it that way. 3rd parties use it, and do not need to care where they will find it, every properly installed system has it at /lib/udev/. /lib64/ is for libraries, we do not ship any, and if we do, we sure will put them in /lib64/, and not in /lib/udev/. But still, only the libs, not any other files. As long as people do not have /sbin64/ and such, the whole discussion about multi-arch for non-libraries is completely superfluous anyway. Matthias, Doug, it would be nice, if you can fix the udev package on Gentoo, it is broken to use /lib64/udev/. Btw, where are your kernel modules? In /lib64/modules/?
