I like busybox but I am not sure that busybox tools will always produce the same result as their fat counterpart. It is likely you may encounter some issues when compiling new packages. bb sed sometime fail like recently http://busybox.net/downloads/fixes-1.20.0/busybox-1.20.0-sed.patch Anyway busybox code is well maintained and more testing should made busybox better. Since some years ipcop build system package the toolchain in a tar.bz2, so I could choose to build chap6 fast or chap5+chap6. The only drawback from this packaged toolchain is that if I patch glibc, I need the exact same glibc from chap5 and chap6. The reason is that tcl/expect/dejagnu are only build in chap5 and I am testing some BLFS packages with chap5 tcl. With a different glibc, segfault may happen. Maybe that's not so wise to test BLFS with chap5 tools, I have many tcl warnings with krb-1.9.3 but I haven't yet found the time to test if rebuilding tcl/expect/dejagnu after chap6 solve those warnings. With a packaged toolchain and ccache, build is much faster for sure. ccache divide by 3 a kernel rebuild time.
