Building FreeBSD

Check out the build scripts, then check out FreeBSD-HEAD, then cd into your FreeBSD-HEAD checkout, and:

$ sudo mkdir /tftpboot ; sudo chown (yourusername) /tftpboot $ /path/to/build/bin/build ap135 $

The tftpboot kernel (kernel.AP135); compressed kernel (kernel.AP135.lzma.uImage) and compressed rootfs (mfsroot-ap135.img.lzma) are placed in /tftpboot/.
