Let's see.

firewalld. Yet another netfilter/nft frontend. One of favorite Red Hat
toys.

pacemaker. For those who think that cluster is "it's not down if it's
restarted on a neighbour host".

nfs-ganesha. Userspace NFS server, designed to be run in a container.
Slow as a snail, but is useful to somebody. 

teamd. Linux bonding has a huge implementation deficiency - it does not
depend on dbus :) This one does.

avahi-daemon. Was mentioned in this very thread.


And last, but not least - any terminal server, like LTSP.
