Hi, I'm trying out grub2 for the first time on my old laptop. I'm following the guide at: https://wiki.gentoo.org/wiki/GRUB2_Quick_Start which seems easy enough. Basically just emerge it, install and go.
However... two different questions: When I did this from a chroot, I just got the GRUB> prompt upon rebooting... no menu or anything. I can manually type "linux /boot/vmlinuz root=/dev/sda3" and then boot into my system. When I run grub2-mkconfig from within the chroot, I don't get any "Found linux image" lines. It does not create /boot/grub2/grub.cfg but rather grub.cfg.new. So I don't know if it's confused about where /boot is or what. Is there a trick to installing/updating grub2 config from within a chroot? Second, when running grub2-mkconfig from within my working gentoo system, it fails with "error: failed to get canonical path of /dev/root." which is apparently because I don't use an initramfs. I must manually run "ln -s /dev/sda3 /dev/boot" before it will work. Is there any trick to avoid having to do that every time? For now I have simply added that to my after-kernel-update script but I'm curious to know if grub2 knows how to handle this on its own somehow. Thanks, Paul
