I am very very slowly working my way through the JH branch with a very very small PowerPC based machine. http://www.blastwave.org/dclarke/efika/efika_002_m.jpg This little thing has 128 MB of memory and a 5400 rpm laptop type Seagate drive on it. I am in chapter 5, well I just finished chapter 5 actually. I am connected to it via a serial line console and I have a DEC VT220 Terminal vesta:~# uptime 12:25:24 up 11 days, 1:02, 1 user, load average: 0.00, 0.00, 0.00 vesta:~# who root ttyPSC0 2008-04-07 17:56 vesta:~# vesta:~# cat /proc/cpuinfo processor : 0 cpu : G2_LE clock : 396.000000MHz revision : 1.4 (pvr 8082 2014) bogomips : 65.53 timebase : 33000000 platform : Efika machine : EFIKA5K2 CHRP PowerPC System revision : 2B3 vendor : bplan vesta:~# df -h $LFS Filesystem Size Used Avail Use% Mounted on /dev/sda3 3.9G 3.1G 667M 83% /mnt/lfs vesta:~# The process has been, what word shall I use?

The testsuite was another twelve to sixteen. I don't know which and I may be guessing. Everything works as is should and I am about to venture into Chapter 6. As a personal note, I can tell you that I do have access to some really screaming fast hardware but where is the fun in that? That is like showing up at a community racetrack with a Maserati MC12 and it will be fancy and slick for some people to look at but no one is really impressed. If you can push an old 1976 Ford Pickup truck over the quarter mile un less than 12 seconds then you have done something interesting there. Perhaps even bizarre. I am doing my first LFS build in five or six years and I chose this little ppc unit to do it with. Because of what LFS is really about, to me, is learning and seeing each piece along the journey.
