If you don't mind, please re-send it. Please c/c me, as we're having some troubles with patchwork nowadays. >> Not all distros use /lib for it.

We've packaged v4l-utils for RHEL, via epel[1]. I volunteered to maintain it for RHEL6, as I use it on my machine and I would be doing it anyway for me, so better to maintain it for the others also ;) [1] https://admin.fedoraproject.org/pkgdb/acls/name/v4l-utils I don't intend to maintain it for RHEL5, but I was told that lots of mythtv users run CentOS (based on RHEL5). So, I won't doubt if someone from CentOS (or other rpm repos for .el5, like atrpms) would add v4l-utils there. >> In a matter of fact, looking at RHEL6 (udev-147-2.35.el6.x86_64), it has >> both.

Do you know, by any chance, what's the minimal udev version where /lib/udev exists? If it is too old, then I agree that pointing the default to /lib/udev is the better. >> The default is a matter of personal taste.
