--U+z1uOwmvmmbFBAc Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable On the two machines where I track head daily, I had failures during "make buildworld" ... in different places on the two machines; re-trying the build succeeded (in each case). Lately, I have (also) been tracking head on these machines with /etc/src.conf augmented with: # For Lua loader experiments WITHOUT_FORTH=3Dyes WITH_LOADER_LUA=3Dyes (on a separate slice, so each machine is booted to that environment and an upgrade-in-place build is done). Curiously, no failures were observed in the case where he Lua loader is being used & built. (I am explicitly NOT claiming any causal relationship here.) I have copied the build typescripts for each combination of machine and boot loader, together with the associated /etc/make.conf, src.conf, and src-env.conf for each to my Web server. The build typescripts also have compressed copies -- the Web server is on the "consumer" end of a residential ADSL: it works, but it's not fast.

Peace, david --=20 David H. Wolfskill david@catwhisker.org Yes, the indictments don't "prove" guilt; that's what trials are for.
