25 The PS3 "port" (stage 4) that you're talking about was a test build done
26 by one of the PowerPC team developers, Brent Baude, and isn't an
27 official release, (as far as I know).
28
29 As for a real port, the basic install can be easily done with the
30 generic ppc/ppc64 stages that we already make! Simply install the
31 stage3, and recompile the whole system using "emerge world -Duve",
32 although you may want to rebuild the system targets first. There is no
33 need for additional stages. By giving you the ability to install on a
34 multitude of targets, while still allowing for optimization and
35 configuration, well, that seem like it meets the Gentoo ideals and
36 philosophy!
37
38 That said, we probably do need to make an updated minimal install CD for
39 PS3 if one doesn't already exist. Unfortunately, the PPC team doesn't
40 have a whole lot of man-power at this time, so that will get done as
41 soon as someone decides that it needs to be done and has the time to do it.
42
43 Again, you can use *any* LiveCD (even other distros!) to boot the
44 system, but the current PowerPC stages are adequate to complete a fully
45 optimized Gentoo on PS3 install.
46
47 Hope that helps,
48 -Joe
