Hello List Mates, I guess most of you have noticed that FailSafe or Safe-Mode has been replaced by Recovery Mode. Isn't Recovery Mode the same as Rescue? Recovery and Rescue boot to init 1. Is this because we are using Grub2? Can someone clarify the reason for the change? Cheers! Roman --------------------------------------------------------------- openSUSE -- Get it! Discover it!

# cat /boot/grub/menu.lst

That's because it's GRUB, not GRUB2. Here is the equivalent section from GRUB2, showing the "recovery" section where "failsafe" should be. ### BEGIN /etc/grub.d/10_linux ### menuentry 'openSUSE, with Linux 3.4.2-1-desktop' --class opensuse --class gnu-linux --class gnu --class os { load_video set gfxpayload=keep insmod gzio insmod part_msdos insmod ext2 set root='(/dev/sdf,msdos3)' search --no-floppy --fs-uuid --set=root 869925e2-39e1-4657-a9b7-fcf317ae1e4a echo 'Loading Linux 3.4.2-1-desktop ...' linux /boot/vmlinuz-3.4.2-1-desktop root=UUID=869925e2-39e1-4657-a9b7-fcf317ae1e4a video=1920x1080 resume=/dev/disk/by-id/ata-Maxtor_6Y120M0_Y3K236RE-part5 splash=silent quiet showopts echo 'Loading initial ramdisk ...' initrd /boot/initrd-3.4.2-1-desktop } menuentry 'openSUSE, with Linux 3.4.2-1-desktop (recovery mode)' --class opensuse --class gnu-linux --class gnu --class os { load_video set gfxpayload=keep insmod gzio insmod part_msdos insmod ext2 set root='(/dev/sdf,msdos3)' search --no-floppy --fs-uuid --set=root 869925e2-39e1-4657-a9b7-fcf317ae1e4a echo 'Loading Linux 3.4.2-1-desktop ...' linux /boot/vmlinuz-3.4.2-1-desktop root=UUID=869925e2-39e1-4657-a9b7-fcf317ae1e4a single echo 'Loading initial ramdisk ...' initrd /boot/initrd-3.4.2-1-desktop } -- Graham Davis, Bracknell, Berks. openSUSE 12.2 B2 (64-bit); KDE 4.8.4; AMD Phenom II X2 550 Processor; Video: nVidia GeForce 210 (using nouveau driver); Sound: ATI SBx00 Azalia (Intel HDA); Wireless: BCM4306 -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Yes. :( The crap is it didn't offer dedicated commandline settings for "recovery" mode. The only one it offered for recovery mode is "GRUB_CMDLINE_LINUX" which applies to regular boot entries as well. (You could check /etc/grub.d/10_linux) However we could invent one for this purpose, name it like GRUB_CMDLINE_LINUX_RECOVERY, if the patch could be accepted by grub2 maintainer, the work could continue in yast to set the failsafe commandlines. I'll try if I can make it. Thanks, Michael
