Thanks Neil, I tried your patch
(http://git.linux-nfs.org/?p=steved/nfs-utils.git;a=commit;h=5e60e38aa4ba251ef66610514be5f45c41519e0f)
and it works for me (at least there is no modprobe failure, I don't have a NFS
test setup), but as a minor nitpick it still causes a log entry because stderr
is not redirected to /dev/null:

> Jul 04 08:13:17 localhost dracut-pre-udev[322]: sh: line 1: /sbin/sysctl: No such file or director

How about something like:

install sunrpc /sbin/modprobe ... && { /sbin/sysctl ... 2>/dev/null ; exit 0 ;
}
