XBMC ~ # cp /proc/mounts /etc/mtab
XBMC ~ # grub2-install /dev/sda
Installation finished. No error reported. |

Polecenie grub2-mkconfig
| Code: |
XBMC ~ # grub2-mkconfig -o /boot/grub2/grub.cfg
/usr/sbin/grub2-probe: error: failed to get canonical path of /dev/root. |
Co ciekawe jak schrootowałem system z płyty Gennto liveDVD
| Code: | | swapon /dev/sda2 && mount /dev/sda5 /mnt/gentoo && mount /dev/sda1 /mnt/gentoo/boot && cp -L /etc/resolv.conf /mnt/gentoo/etc/ && mount -t proc none /mnt/gentoo/proc && mount -o bind /dev /mnt/gentoo/dev && chroot /mnt/gentoo /bin/bash |
tak wiem, leniwy jestem . Komenda "grub2-mkconfig -o /boot/grub2/grub.cfg" działa poprawnie. Co mam zrobić żeby móc modyfikować grub-a z poziomu systemu?.
