Hi, Mark H Weaver skribis: > # Set 'root' to the partition that contains /gnu/store. > -search --file --set /gnu/store/21ngnlx9k0x9x2jj1px7mdlb4j6mzz6x-grub-2.02/share/grub/unicode.pf2 > +search --label --set /dev/mapper/jojen-root Oops. I believe the patch below does the trick (‘store-device’ must never be a Linux device name, and that’s what the patch ensures.) Thoughts? (I didn’t notice these issues because I identify my root file system by label or UUID rather than hard-coding its /dev/mapper name.) Ludo’.
