Eudev does not use /lib/udev/devices

Reported by: Chris Staub Owned by: bdubbs@…
Priority: normal Milestone: 7.6
Component: Book Version: SVN
Severity: normal Keywords:


All devices are initially created in /dev by the devtmpfs, so Eudev doesn't copy anything from /lib/udev/devices anymore.

This change also needs to modify the mountvirtfs boot script, removing line 60:

cp -a /lib/udev/devices/* /dev

If the attached patch to the book is implemented without that, I think it will throw an (ignored) error because /lib/udev/devices/ will not exist.

I don't see that line in the script, except in the bootscripts version for LFS 7.5.

Disregard my comment. I looked on an older system.

Hmm. I am pretty sure nothing in the kernel fits this description, but aren't there out-of-tree drivers that don't integrate with devtmpfs and thus still require manual device node creation?

For that matter, what creates /dev/pts before devpts is mounted there?

The book doesn't need the static nodes, but I'm thinking it may be good to keep the option as an escape hatch...

Perhaps we should remove /lib/udev/devices from the book for now, but leave it in the xml commented out. Then, if something comes up, we can easily restore it. Right now, I don't know of any reason to leave it in the book.

We do create /dev/pts in the mountfs boot script if it doesn't exist.
