(menu-entry->sexp, sexp->menu-entry): Support chain-loader. * doc/guix.texi (Bootloader Configuration): Document it. Co-Authored-By: Julien Lepiller --- v2: Correct the document and specify all fields of in the pattern of menu-entry->sexp. Now still judge linux, multiboot-kernel and chain-loader. Because if don't judge, the menu-entry that all of linux, linux-multiboot and chainloader are #f will match the first one. Then produce Error message: guix system: error: #: invalid G-expression input This error message does not help. v3: correct the document and delete an extra blank line. v4: Add check for initrd in menu-entry->sexp, which is a change moved from the third patch of v3. all: The documents are mainly corrected by Julien Lepiller.
