 # TODO: Either fix per profile masking in overlays, or move
 # relevant entries to the relevant package.mask files in ::gentoo
 
+# Note: Do not use `Closes:` tag when treecleaning a package. Instead
+# use the `Bug:` tag and use the RESOLVED/PKGREMOVED status on
+# the bug manually if you can, or wait for someone else to do it.
