Will Woods' comment:

I'm 98% sure this is caused by a bug in dracut, which should be fixed by this
patch: http://article.gmane.org/gmane.linux.kernel.initramfs/2639

* Using a kickstart with "network --device=link" causes parse-kickstart to
write "ip=..." args to /etc/cmdline.d, then unset CMDLINE
* The bug with _getcmdline causes the "ip=..." arg to get duplicated
* "getargs ip=" returns the duplicated "ip=..." args, and then the network
module dies with the "Please supply bootdev argument for multiple ip= lines"
error.
