[gentoo-user] Booting the Kernel as UEFI App

[gentoo-user] Booting the Kernel as UEFI App

Hi Guys,

I just got my laptop back from repair, the main board and harddrive are
changed, so bye bye data. I haven't created any data on gentoo, i couldn't
even set up the system before it crashed.

So I'm going to setup a new install, and I have heard that you can set up
the kernel as UEFI application[1]. I have booted the system from UEFI grub2
before, so UEFI works and I know that the BIOS/UEFI has a boot manager.

Has anyone here did this before or is this a bad idea ?

I haven't used UEFI before, but won't making a Gentoo kernel means more
trouble when you need to update?

I think letting grub2 be the UEFI app, then from there make grub2 boot
Gentoo, would be preferable. You can then prepare 3 images for booting:
Known Good, Previous Known Good, and Newest Testing. Once Newest Testing is
confirmed to run well, Previous Known Good can be retired, Known Good
demoted to Previous Known Good, and Newest Testing graduated to Known Good.

Again, I have no experience with UEFI, so I am also interested if anyone
can shed more light on this.

Rgds,
