Normally all other modules and configuration files are searched for relative to $prefix. grub always needs to know $prefix value which is why it is mandatory. > --- > > Appendix > > config file: > > ~~~ > $ cat out/grub.configfile > search.fs_label rootfs root > set prefix=($root)'/boot/grub' > configfile $prefix/grub.cfg > ~~~ > > grub modules: > > ~~~ > GRUB_MODULES="boot chain configfile echo efinet eval ext2 fat font > gettext gfxterm gzio help linux loadenv lsefi normal part_gpt part_msdos > read regexp search search_fs_file search_fs_uuid search_label terminal > terminfo test tftp time xen_boot" > ~~~ > > best regards > J.
