FYI ----------------- For grub-1.98 !!! -----------------
http://ubuntuforums.org/showthread.php?t=1195275 describes a way to save the last chosen boot option to default Involved is /etc/default/grub file which must be user created: ============================================== cat > /etc/default/grub << EOF # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. GRUB_DEFAULT=saved GRUB_SAVEDEFAULT=true #GRUB_HIDDEN_TIMEOUT=0 #GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 #GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` #GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries GRUB_DISABLE_LINUX_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" EOF ============================================ There is no silly update-grub command, so use grub-mkconfig to update. ------------------------------------ For grub-1.98, there is broken build http://www.mail-archive.com/grub-de...@gnu.org/msg15254.html ------------------------------------ One solution that worked is to NOT build in a separate build directory. E.g., instead of: mkdir build cd build ../configure --bla-bla-bla make Do: ./configure --bla-bla-bla make ---------------------------------------- Grub-1.98 puts 3 lines in a common area which can (should?) be removed in the individual "menuentry" blocks: insmod ext2 set root='([drive],[partition])' search --bla-bla-bla Since the search is redundant of set root, it is not necessary. Since the silly 'echo Loading linux ...' will scroll off almost immediately it is not necessary. The resulting grub.cfg I got (after removing redundant and silly) was: ============================================= # # DO NOT EDIT THIS FILE # # It is automatically generated by /usr/sbin/grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ]; then load_env fi set default="${saved_entry}" if [ ${prev_saved_entry} ]; then set saved_entry=${prev_saved_entry} save_env saved_entry set prev_saved_entry= save_env prev_saved_entry set boot_once=true fi function savedefault { if [ -z ${boot_once} ]; then saved_entry=${chosen} save_env saved_entry fi } insmod ext2 set root='(hd4,10)' search --no-floppy --fs-uuid --set 11b62acd-ee91-43f7-a619-c4b5cb5fa5e7 set locale_dir=($root)/boot/grub/locale set lang=en insmod gettext set timeout=10 ### END /etc/grub.d/00_header ### ### BEGIN /etc/grub.d/10_linux ### menuentry "GNU/Linux, with Linux 2.6.33.5" --class gnu-linux --class gnu --class os { savedefault linux /boot/vmlinux-2.6.33.5 root=/dev/sdd10 ro } menuentry "GNU/Linux, with Linux 2.6.33" --class gnu-linux --class gnu --class os { savedefault linux /boot/vmlinux-2.6.33 root=/dev/sdd10 ro } menuentry "GNU/Linux, with Linux 2.6.32.8" --class gnu-linux --class gnu --class os { savedefault linux /boot/vmlinux-2.6.32.8 root=/dev/sdd10 ro } ### END /etc/grub.d/10_linux ### ### BEGIN /etc/grub.d/30_os-prober ### ### END /etc/grub.d/30_os-prober ### ### BEGIN /etc/grub.d/40_custom ### # This file provides an easy way to add custom menu entries. Simply type the # menu entries you want to add after this comment. Be careful not to change # the 'exec tail' line above. ### END /etc/grub.d/40_custom ### ========================================================= This has some variance with what is in lfs/dev for grub-1.98. Those --class businesses are probably silly. I (think) used this sequence which produced a good result: * create /etc/default/grub * grub-install --grub-setup=/bin/true /dev/sdd * grub-mkconfig -o /boot/grub/grub.cfg I rebooted and chose menuentry "GNU/Linux, with Linux 2.6.33" and (amongst other grub garbage) /boot/grub/grubenv contained: saved_entry=GNU/Linux, with Linux 2.6.33 On subsequent reboot, this was the default. The lfs/dev updated language involving search looks sensible. -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
