 |
|
Hello,
I'm trying to install grub2 on a new install which uses luks to encrypt the root filesystem. However I am hitting a snag:
| Code: |
livecd ~ # grub2-install /dev/sda
Installation finished. No error reported.
livecd ~ # grub2-mkconfig -o /boot/grub/grub.cfg
/usr/sbin/grub2-probe: error: failed to get canonical path of `/dev/mapper/root'.
livecd ~ #
|
Where /dev/mapper/root is decrypted /dev/sda4
The problem basically boils down to:
| Code: |
livecd / # grub2-probe --target=fs /
grub2-probe: error: failed to get canonical path of `/dev/mapper/root'.
|
Environment outside of chroot:
| Code: |
livecd gentoo # mount

Does this mean I have to edit /etc/default/grub in some way in order to make grub2 understand what is going on? Thanks in advance. |
