This is a big change on saving a default entry. This change makes it possible to set up a quite robust system using GRUB. Now we do not use the second sector of Stage 2 to store an entry number but use the file /boot/grub/default. This file must be generated by grub-set-default, although this file is plain-text. * util/grub-set-default.in: New file. * util/grub-install.in (grub_set_default): New variable. Use /grub instead of /boot/grub on OpenBSD as well as NetBSD. Run grub-set-default to make a default file. * util/Makefile.am (sbin_SCRIPTS): Added grub-set-default. * stage2/stage2.c (run_menu): Change the fallback handling to support multiple fallback entries. (cmain): Likewise. Also, get a saved entry from a default file if possible, before reading a config file. * stage2/shared.h (DEFAULT_FILE_BUF): New macro. (DEFAULT_FILE_BUFLEN): Likewise. (CMDLINE_BUF): Set to DEFAULT_FILE_BUF + DEFAULT_FILE_BUFLEN. (MENU_BUFLEN): Set to 0x8000 + PASSWORD_BUF - MENU_BUF. (fallback_entry): Removed. (fallback_entries): Declared. (fallback_entryno): Likewise. (MAX_FALLBACK_ENTRIES): New macro. * stage2/cmdline.c (run_script): Use FALLBACK_ENTRYNO instead of FALLBACK_ENTRY. * stage2/builtins.c (fallback_entry): Removed. (fallback_entryno): New variable. (fallback_entries): Likewise. (init_config): Initialize FALLBACK_ENTRYNO and FALLBACK_ENTRIES. (fallback_func): Rewritten completely. (savedefault_func): Likewise. * docs/grub.texi (grub-set-default): New direntry. (Installation): Describe grub-set-default for manual installations. (Making your system robust): New section. (Booting once-only): New subsection. (Booting fallback systems): Likewise. (fallback): Describe multiple fallback entries. (savedefault): Describe an optional argument. (Invoking grub-set-default): New chapter. (Future): Replaced with a description about GRUB 2. * configure.ac (AC_CONFIG_FILES): Added util/grub-set-default.
