-Keep or drop the yum cache.
+Keep or drop documentation, man pages and info files.
=item B<--keep-cracklib>
Keep or drop all timezones (except UTC which is never deleted).
+=item B<--keep-rpmdb>
+
+=item B<--drop-rpmdb>
+
+Keep or drop the RPM and YUM package databases. Obviously RPM and YUM will be
+completely non-functional if you drop these.
+
+=item B<--keep-yum-cache>
+
+=item B<--drop-yum-cache>
+
+Keep or drop the yum cache. Note that L<febootstrap(8)> has already
+deleted this directory unless you ran it with the C<--no-clean>
+option.
+
+=item B<--keep-services>
+
+=item B<--drop-services>
+
+Keep or drop the C</etc/services> file. If dropped, this file is
+replaced with a very minimal one which just lists the most common
+services. For less common services you will have to refer to them by
+port number instead of name.
+
+=item B<--keep-sln>
+
+=item B<--drop-sln>
+
+Keep or drop C</sbin/sln> (statically linked C<ln>). This is not
+really required in minimal appliances.
+
+=item B<--keep-ldconfig>
+
+=item B<--drop-ldconfig>
+
+Keep or drop C</sbin/ldconfig>, C</etc/ld.so.cache> and
+C</var/cache/ldconfig> (the dynamic linking cache). This is not
+needed. Dynamic linking during program execution will be marginally
+slower.
+
+=item B<--pack-executables>
+
+This option has been removed in febootstrap 2.5. In previous versions
+it was used to pack executables using the external C<upx> program.
+However it was not enabled by default and never worked very
+effectively.
