Re: [gentoo-catalyst] Re: [gentoo-releng] Seek for your advices : Make Gentoo LiveCD for ppc64le

[Kevin Zhao]

Hi Brian & all,
      Now I have successfully made livecd-stage1, compiled some packages
such as app-misc/livecd-tools. After that , I'm working on building gentoo
livecd-stage2 for ppc64le. Now I have a problem and needs your help :-)

      In the file: catalyst/examples/livecd-stage2_template.spec , I see "The
cdtar is essentially the bootloader for the CD.  It also holds the
main configuration
for the bootloader".
Also I see in the releng/
releases/weekly/specs/ppc/ppc64/installcd-stage2-minimal.spec , in the the
livecd/cdtar is yaboot,but yaboot  has not been used in ppc64le . *Now the
bootloader of ppc64le iso is almost Grub*. I have a  problem:
       When I decompressed
the catalyst/livecd/cdtar/grub-memtest86+-cdtar.tar.bz2 , get the
consequence:
          boot/
          boot/grub/
          boot/grub/stage2_eltorito
          boot/memtest86
The grub is the binary . So If I want to use the grub , how could I build
from the grub source files and replace the grub here? What are the
essential files of grub used here?
       Really Appreciate for your help ~ Big Big Big thanks ~

Best Regards ,
Kevin
