Keith ... I'm currently running a 3.10 kernel on Centos6, but I keep
running into udev issues. What I found was the sysfs has changed
significantly enough from 2.6.32 to 3.10 that SUBSYSTEM references in udev
rules no longer resolve properly. For home use, this may not be too
noticeable, but our application relies heavily on udev.

For my needs to be met, I'm going to need a 32bit enterprise linux 7
derivative ...  CentOS or otherwise. Rather than just hope it will happen
eventually, I'm trying to get involved. There were some good pointers on
things that need done already mentioned, and come mid-august I'm going to
be devoting a fair amount of time to these. If you guys all have other
solutions that work for you instead of a 32 bit EL7, that's great. My
project needs EL7 32 though, so that means I'm making something work one
way or another. Just figured there were others in the community that had
similar needs.
