Hi. The 7.2-1 kernel package for kfreebsd-i386 is currently in NEW. !!! Do not install it !!!
I would just say "important" as it prevents only 32-bit binaries to work, 64-bit binaries works for me for weeks ...This prevents almost all biarch packages to be built, including glibc, gcc, gcj, gdc, etc. I had to downgrade the kernel on the build daemons to version 7.1 to get those packages built.
It prevents all 32-bit binaries to work, on kfreebsd-i386 it means whole system. So, it is really "grave".
I am fine with removing the check for now (or maybe removing BI_BRAND_NOTE from sys/amd64/linux32/linux32_sysvec.c), I was more speaking about a more long term solution that may be merged upstream, like checking the OS field correctly.
I have a slightly hackish patch with the check of the OS field. After test on kfreebsd-i386 I will put in our SVN. Petr
