Are you referring to grub figuring it out when booting or to grub figuring it out while it's being installed? (In any case, I don't know any of the answers ...) There needs to be a way for grub to figure out where to look for its configuration. Perhaps this information is stored in the MBR when installing grub. In that case, you would have a problem when grub cannot find its configuration there anymore (like because the partitioning has changed) and maybe a problem if it finds the wrong configuration. -- Debian testing amd64 -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
