genhomedircon is looking for a conflict of the labeling of the parent
directory.
For app is wants to label /var/lib as home_root_t, but it sees a
conflict in that /var/lib has a label in file_context file of var_lib_t.
So it complains.
For /var/lib/application/ftproot it looks for /var/lib/application in
the file_context file, and does not find the line so it can label
/var/lib/application as home_root_t and it is successful. I think in
neither case you want those labels.
genhomedircon identifies "Real Users" As any user with a UID > 0 and a
shell in /etc/shells and not the shell /bin/false or /sbin/nologin.
