install nfs modprobe config file
For nfs4, in case nfs.ko is not loaded mount.nfs4 will try to load
nfs4.ko instead of nfs.ko. Fedora nfs-utils creates a lib/modprobe.d/nfs.conf
in which there's below alias:
alias nfs4 nfs
Dracut also need this file to auto load nfs kernel module.
Tested booting to a fedora 17 nfsroot share.

Hmm... that modprobe.d conf file should have been already copied to the initramfs:
modules.d/90kernel-modules/module-setup.sh: dracut_install $(find -L
/etc/modprobe.d/ -maxdepth 1 -type f -name '*.conf')
Oh.. I see ... it's /lib/modprobe.d and not /etc/modprobe.d

Yeah, should consider /lib/modprobe.d as well:

Yes, then should update the 90kernel-modules instead. but if the
distribution does not ship the nfs.conf, this will still be a problem, I
think 95nfs should also add the alias file in case ! -f
/lib/modprobe.d/nfs.conf, what do you think?

It's ok to install the /lib/modprobe.d/*.conf, but for nfs alias as I
said better to create the nfs.conf in case there's no such file..
