Thanks for your report. We really hope libc6-i686 package which is currently dropped because of its brokenness. > A few little problems I noticed: > > - I think the .postinst is really supposed to be the .postrm What does this mean? > - libc6-i686 contains /lib/ld-linux.so.2, which conflicts with > libc6.

Ah, packages.d/optimized.mk says "-O99" :-) IIRC, -O6 is the max valid value. BTW, If "-O3" causes problems, gcc may have bug, I guess. > After fixing those, it seems to be rather stable. > > I wish I could say that I see massive performance improvements, but > I don't. Preparing optimization packages is one of our goal. -- gotom
