[gentoo-dev] Gentoo Kernel Installation Doc

[Yannick Koehler]

I think it would be nice that I could take the kernel from the LiveCD and 
installed it as is (including moduels) over my new installation PC instead of 
building a new one.  For sure I would like to do that past the first reboot 
but I often got problems where I forgot some required kernel option rebooting 
into a "Missing console" kernel critical stop or into a "Missing DevFS" 
state.

Then I have to reboot from the CD, remount everything as it was, chroot and 
recompile ...  It would be really great that the installation start by having 
you install the LiveCD kernel with the module get this to be the default 
kernel for your installation then once rebooted to that new kernel from the 
hard disk you could then start installing/playing with a new version of the 
kernel.

At least at that point if the new kernel failed, a simple reboot with the 
selection through grub/lilo to pick the previous working kernel would be 
enough to get you back inside a working state to debug your kernel.

That installation could also be simplified by creating an ebuild such as 
livecd-kernel and having the admin type emerge livecd-kernel to do that step 
for him.

This would also make it easier for an installation software to get that step 
automatically done.

I tend to agree with this, as it would also eliminate a problem I ran into
(which I'm assuming will get fixed for the final 1.4 release):

The 1.4 RC2 CD boots with a 2.4.20 kernel, which happens to recognize and
support the nVidia ethernet port on my Asus A7N8X motherboard (later version
of the 2.4.20 kernel also recognize the 3COM ethernet port, but alas.. I need
only one port to get gentoo going).  After the gentoo install was completed
and I rebooted, I ended up with a 2.4.19 kernel, which doesn't support either
of the ethernet ports without being patched.

Once a new kernel is compiled, the install kernel could be added as a
"fail-safe" backup kernel to the boot menu.

So Copy it over, nothing relly hard about that, tho i am a firm bealiver
that you should know your machine enough to be able to compile a kernel
for it. tho having it do this automaticly would relly take away the
apeal of gentoo for me, i like to be in control, and using some yuppies
pre-fab kernel, with things he thinks i should use, that would just take
up precious HD space, is not the gentoo way.
