Talk:GRUB2 Migration

device.map is not accurate
I have encountered the issue that the contents of device.map does not reflect the actual device map, and I had to run 'grub-install --recheck /dev/sda'. Mimosinnet 20:38, 24 February 2014 (UTC)

/dev/sda does not work in some cases and should target /boot partition, not device
When upgrading from grub legacy to grub 2, targeting /dev/sda (where my personal /boot is located) did not work. I had to directly target /dev/sda3 (partition where my bootloader is located) and enable --force because I am using ext2. Simply targeting /dev/sda did not install grub2 for me. — The preceding unsigned comment was added by Stedlev (talk • contribs) 25 September 2014

USE flags?
Shouldn't this guide mention the USE flags when emerging the package — like "emu" for BIOS-based amd64, as discussed at GRUB2? - dcljr (talk) 05:20, 6 January 2017 (UTC)


 * What exactly is "emu" for? I haven't been able to find relevant documentaion on it. Ironic, since GRUB2 shows it can be used on any supported CPU... - dcljr (talk) 09:21, 6 January 2017 (UTC)
