So it's better to be sure...
I think so too. What may appear to be a gratuitous rebuild of llvm, for example, is in fact meta mode rebuilding because of some makefile change. Without meta mode I've experienced odd weirdnesses that are fixed through a subsequent clean build. I just started using meta mode again this week after a few years hiatus to see if it addresses the occasional weird behaviour due to something not being rebuilt when it should have been. -- Cheers, Cy Schubert <cy.schub...@cschubert.com> FreeBSD UNIX: <c...@freebsd.org> Web: http://www.FreeBSD.org NTP: <c...@nwtime.org> Web: https://nwtime.org e^(i*pi)+1=0
