I do not think that is the, it in fact the case! I rebuild first everything after "make cleanworld"; then I did the same again, no update, no nothing done after that build (filemon already loaded as it was prerequisite for the first run!); surprisingly, the build ran again full time starting from scratch! I'm able to reproduce this behaviour easily: make cleanworld; kldload filemon (if not already loaded); make buildworld buildkernel After the build has finished, install everything accordingly and reboot. Then kldload filemon and make buildworld buildkernel in /usr/src - and be surprised. > > > These setting dind't change over the past time, except some WITHOUT_ tags. > > > > Are there any unrevealed secrets? > > If changing any of those knobs impacts CFLAGS etc - then pretty much > everything will be out-of-date. > > Adding -dM to your build command should be very instructive. > _______________________________________________ > freebsd-current@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org" - -- O.
