Yes, I think this is done in /usr/src/Makefile.inc1 where the correct GENERIC file in /usr/src/sys/i386/conf or /usr/src/sys/amd64/conf is then selected. > You have to explicitly set it to cross-build, and I > find it hard to believe that someone would set TARGET/TARGET_ARCH to > amd64 by mistake In case of a crossbuild, I assume the system would also do the proper "TARGET magic" to use the GENERIC corresponding to the requested architecture. > I think it's likely that it is a 64-bit installation. Not sure about that. How could the amd64 OS be installed and run on a i386 machine? -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
