Hi, |
2 |
|
3 |
I'm trying out grub2 for the first time on my old laptop. I'm |
4 |
following the guide at: https://wiki.gentoo.org/wiki/GRUB2_Quick_Start |
5 |
which seems easy enough. Basically just emerge it, install and go. |
6 |
|
7 |
However... two different questions: |
8 |
|
9 |
When I did this from a chroot, I just got the GRUB> prompt upon |
10 |
rebooting... no menu or anything. I can manually type "linux |
11 |
/boot/vmlinuz root=/dev/sda3" and then boot into my system. When I run |
12 |
grub2-mkconfig from within the chroot, I don't get any "Found linux |
13 |
image" lines. It does not create /boot/grub2/grub.cfg but rather |
14 |
grub.cfg.new. So I don't know if it's confused about where /boot is or |
15 |
what. Is there a trick to installing/updating grub2 config from within |
16 |
a chroot? |
17 |
|
18 |
Second, when running grub2-mkconfig from within my working gentoo |
19 |
system, it fails with "error: failed to get canonical path of |
20 |
/dev/root." which is apparently because I don't use an initramfs. I |
21 |
must manually run "ln -s /dev/sda3 /dev/boot" before it will work. Is |
22 |
there any trick to avoid having to do that every time? For now I have |
23 |
simply added that to my after-kernel-update script but I'm curious to |
24 |
know if grub2 knows how to handle this on its own somehow. |
25 |

Thanks, |
