Hi  Mike && Hi Folks,
      First I want to thanks for your help and advices , we have finish
make gentoo stage3 and it will be tests by our community.
      Now I  am working for  gentoo LiveCD using stage3 .   After searching
gentoo website, I can not find a very clearly method to make gentoo LiveCD
.
      So ,if conveniently , could you give me some advices or some websites
which cover the methods to LiveCD of other arch(e.g : x86 ,amd64 etc..)
      Thanks very much ~   :-)

You can find in the releng repo the specs we use to build all the
stages and CDs for all the arches[1]. In particular you might want to
use something like the install-cd specs for amd64[2][3] as examples.
We also have some scripts in the repo we use for the automated builds
in some arches[4].
Feel free to poke us through e-mail or pop into #gentoo-releng in the
freenode network.

Hi Jorge,
     Really thanks for your suggestion😁
     I see in the spec that the filesystem type is squashFS. And I want to
compress the Gentoo  stage3 of ppc64le  to the squashfs filesystem ,so that
I can control the image size. Do you have any tips for me ? Thanks very
much!

Use catalyst-9999 which has the new compress/decompress handling code.
then in your spec file:

compress_mode = squashfs

That's it

Hi Brian,
     Big Thanks~
     I see the releng direcctory, find th at the spec of ppc64 just support
BE ,and the bootloader is yaboot.  So I will use a new spec reference to
the ppc64 BE spec, modify the bootloader as grub ,arch type and use the
stage3 I have just compilied to build livecd. If I have more progress I
will put here .Thanks ~

[-- Attachment #1: Type: text/plain, Size: 4098 bytes --]

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

We've been talking about how to improve this as we're basically using a 
binary in the catalyst package to build the CD instead of building it from 
source.

I can share with you some scripts I've used to build the cdtar for 
myself[1].
IIRC, I've used it to update the cdtar in catalyst sometime ago.
These have quite a few hardcoded paths, make a few assumptions and are 
meant for building the cdtar for x86 / amd64, but they might be able to 
give you some ideas.

[-- Attachment #1.1: Type: text/plain, Size: 3109 bytes --]

Hi All :
     Long Time No See~Hope everything goes well:-)
     Recently I am working on making ppc64le Gentoo Livecd. Now the newest
status is as below:
     1 .I have followed catalyst , build--> livecd-stage1 and
livecd-stage2.
     2. Replace the bootloader from yaboot to grub.
     3. The grub binaries I have copyed from Rhel7.1-ppc64le
     4. Change the boot_info.txt to a new one from Rhel7.1-ppc64le
     5. Build a squashfs images.
     6. Build a kernel and initramfs (I have check that the kernel is good
when using it replace a ubuntu-ppc64le kernel .)
     7. use command "mkisofs -v -r -T -U -l -cache-inodes -chrp-boot -V {
clst_iso_volume_id} -o gentoolive.iso /path/" to generate a Livecd.

    Now when loading iso to a guests, I can enter into grub, but have meet
 problem when initramfs runs:* Couldn't mount /dev/sr0*

The *grub.cfg* file is as below:
=============================================================================================================

set default=0
set timeout=10

echo -e "\nWelcome to the Gentoo PPC64LE!\n\n"

menuentry "Gentoo PPC64LE" {
 * linux /boot/vmlinux-4.2.1-aufs root=/dev/ram0 init=/linuxrc
looptype=squashfs loop=/image.squashfs  cdroot ro
                          *
*  echo 'Loading initial ramdisk ..............'*
*  initrd /boot/initramfs-genkernel-ppc64le-4.2.1-aufs*
}

menuentry 'Reboot' {
  reboot
}

menuentry 'Exit to Open Firmware' {
  exit
}
==============================================================================================================

   I have loaded it with a guest,guest xml file is here(add two iso just
for  compared,one is Gentoo and one is ubuntu ) :
https://bpaste.net/show/271874e8ca8b
   But the initramfs will bolcked when mount cdrom device. The error log
Link is: https://bpaste.net/show/f029aff8e633
   You can see that , mount -t auto /dev/sr0 /mnt/cdrom  failed.
   *Also, I enter into busybox, manally use command "mount -t iso9660
/dev/sr0 /mnt/cdrom", it shows "No such device"*
[image: 内嵌图片 1]
  * ls -l /dev/ :*
*   Find that there are :    "/dev/sr0   /dev/sr1",but there is no
"/dev/cdrom"*
*   But I 'm sure that kernel has the module "sr_mod" and "cdrom". Because
we have used this kernel and stage3 to make a workable gentoo image(running
in KVM).*

*So, *now I am thinking of asking you for some advice.I've blocked here for
about 2 weeks .Any advice will be really appreciated. Loooooooking forwards
to your reponse   :-)
