It seems like an awfully long time ago now. :-) I did it by building Gentoo in armhf mode - *on* my R-Pi 1 - and = distributing the ready-built rootfs. To do this, I simply started from = a softfp Gentoo build, and rebuilt it from the ground up using the Stage = 1 bootstrap method. All the tools and support simply worked from that = point on. At the time, ARMv7 distros were already typically built in armhf mode, = but ARMv6 machines were usually expected to use softfp (or even = softfloat) builds originally intended for ARMv5. Since the R-Pi was = obviously going to be a =E2=80=9Cplatform standard=E2=80=9D and would = always include an FPU, the effort of producing a proper ARMv6-hf build = was justified. - Jonathan Morton
