I have trees that go for years without ever being cleaned. Unless I'm collecting timing data for clean tree builds. If you use DIRDEPS_BUILD as well as META_MODE, there can be cases where you need the stage tree cleaned (staging is like auto-install to DESTDIR). The most common case is when a library has switched from staging its headers from $STAGE_ROOT/$MACHINE/usr/include to $STAGE_ROOT/common/usr/include (so they only get staged once), if you don't clean out $STAGE_ROOT/$MACHINE/usr/include, builds will continue to find headers there that should be found in $STAGE_ROOT/common/usr/include and thus revert Makefile.depend changes. We added a mechanism to allow triggering auto-clean of stage tree when such changes are made. --sjg
