$ rpm -qi nfs-utils|grep ^Size
Size        : 1243512
$ echo $((374573+942088))
1316661

So, they're a little bigger than nfs-utils, taken together.  Like you
say, under development, probably there's just something overlooked that
could be removed from one or the other or moved to an nfs-common
package.

That might make a case for splitting up client and server sides for
minimal installs that need only one or the other.

If it's installed size we're working on, though, do we have some target
in mind here, though?  Do we know what the container people are aiming
for?  I had some idea glic is more in the 10s of megabytes, and a
minimal Fedora install is in the 100s, so I just wonder if it's worth
chasing after 10s-100s of K.
