device-mapper-multipath has an explicit Requires on libudev. Please remove it. udev has been merged into systemd and the libudev package will exist no more. See http://lists.fedoraproject.org/pipermail/devel/2012-June/168227.html Explicit Requires on libraries are always suspicous. See http://fedoraproject.org/wiki/Packaging/Guidelines#Requires device-mapper-multipath-0:0.4.9-26.fc18.i686
Ping! Please rebuild the package, libudev0 will go away soon and the package will no longer work as expected.
Removed the libudev Requires and Buildrequires and replaced them with Buildrequires: systemd-devel
The dependencies of the package in Rawhide look good now. Thanks.
