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.
Migrated to newer autotools. Also, don't install mkbimage
because its name is too general and it does not conform to the
GNU Coding Standards in some points.
* util/Makefile.am (EXTRA_DIST): New variable.
(sbin_SCRIPTS): Removed mkbimage.
(noinst_SCRIPTS): Added mkbimage.
* stage1/Makefile.am (AM_ASFLAGS): Renamed to ...
(AM_CCASFLAGS): ... this.

(xfs_stage1_5_exec_CCASFLAGS): ... this.
(diskless_exec_ASFLAGS): Renamed to ...
(diskless_exec_CCASFLAGS): ... this.

* configure.in: Removed.
