+Subject: [PATCH 079/200] build,rpm: don't try to rm drbdmon.8.gz in preun
+
+This is most likely a fallout from changes introduced in
+f962315c30e901258bd151f33994d85f32905cee
+
+We have "versioned man pages" and create symlinks to them (e.g.,
+drbdmeta.8.gz -> drbdmeta-9.0.8.gz). Creating and deleting these is
+managed in post and preun scripts. drbdmon is special as there is no
+versioned man page, there is only drbdmon.8.gz (the final file, no
+symlinks).
+
+As is, we tried to rm the file twice, once in preun and then as part of
+"files". This resulted in a completely harmless message that a
+non-existent file was tried to get removed.
