[Fedora-livecd-list] /dev/live no longer being created since udev-153 update?

Wed Aug 25 23:58:26 UTC 2010

Aaron,

I am experiencing the same issue and tracked it down to the udev
update just not exactly why.   I reset the overlay and only installed
udev and had the issue on the next boot.

Thanks!
Darren
