Hello: It's time to try running Gentoo again, after over a decade.
I have gone through, I think, the steps, using the Gentoo LiveCD as a launchpad. Installing and configuring Grub has presented a little confusion, regarding the correct boot partition. I have other GNU/Linux installs on this machine; for all of them, I've fallen into the practice of setting up grub in /boot/efi. However, the Gentoo Handbook does not mention this approach, so I tried using just "/boot". As it turned out, when I rebooted---thinking all steps had been completed---the Gentoo system does not appear in the Grub Menu. I have found that manjaro's grub setup has been good at picking up any other installs, and, once a particular one has been booted, manjaro's grub defaults to that other install. Thinking that even if grub is not working, perhaps Manjaro would see Gentoo, I tried that. So far, no luck. I am planning to try to mount the boot partition to /boot/efi, now, and see what happens. Any problems with this? Thank you, -- Alan Davis "The greatness of a nation and its moral progress can be judged by the way its animals are treated.” --- Mahatma Gandhi
