[gentoo-releng] multiple kernels on one livcd?

[Pieter Van den Abeele]

Hi,

I would like to know if it is possible to create a livecd with multiple 
kernels (smp/non-smp, ...)?
This would be beneficial to the mirrors (G5 live environment = G3G4 
live environment). My older scripts do not allow this, because this 
posed problems with gcloop (module had to be compiled against the 
kernel). I believe this should no longer be a problem with latest 
gcloop, which gets patched into the kernel.

yes, catalyst can most definately put multiple kernels on a livecd,
it's very simple as well.  Take a look in
examples/livecd/amd64/amd64-stage2-20040201.spec
And you'll see exactly how to do it.  Also, I committed gcloop and
squashfs support for both genkernel (3.0.1_beta12), and the latest
CVS of catalyst.  I personally couldn't get gcloop working, but
it's very possible there's a problem with amd64 and gcloop.  The
problem occurred when trying to boot, the initrd couldn't properly
echo " " | losetup -e ucl-0 -p0 /dev/loop0 livecd.gcloop
for some reason.  I could not get it to work natively from within
my OS either.  Anyhow, that's a question for lu_zero.

BTW, for gcloop support, set your  cdfs type to 'gcloop' and for
squashfs  to 'squashfs'  .... not that you couldn't have guessed
that ;)

Hi Pieter,

yes, that is possible. However it requires some heavy-fiddling with
3rd-party modules. In the attachment you can see a livecd-stage2 spec
for x86. Should be quite self-explaining.
