I don't think there is a generic way of doing this since yum can
pretty much install anything anywhere and run the postinstall scripts
that might only work on the host where it runs. However, for typical
things it might work to install everything on one host where / is
exported and mounted somewhere on the other systems with PATH and
LD_LIBRARY_PATH tweaked to visit the bin,sbin,usr/sbin,usr/bin and
equivalent library paths on the mountpoint after the local locations.
Things like perl modules will probably become a horrible mess,
though, and other things might need a splattering of symlinks to work.
Might be easier to PXE boot into an NFS-mounted root with DRBL or the
like if you need to save disk space. On the other hand, it's really
not that hard to tell yum on 100 machines to install the package.
