Thread: Change default grub options

    Default Change default grub options

    Hello,

    A few days ago, I installed openSuse 11.2 MileStone7 (now upgraded to 8). I know it is testing.

    The only way to run the installer was in safe-mode. After that, my system is installed and working fine. A minor thing, I used MythTV with NewCS & opensasc. Opensasc won't work with kernel 2.6.31+ so I have to compile my own kernel (2.6.30x). No problem so far, but when it creates a grub entry it always put a lot of options used with the safe-mode installer (I think) like acpi=off and so on.
    But this is not needed anymore! Can it be changed?

    And openSuse always use a nice theme when booting, but with my own kernel it shows a lot of text. How did the do this?

    Thanks.

    Well you can edit the boot arguments manually at the boot screen as you probably know. If what you try works OK. You can edit the file to make it permanent at /boot/grub/menu.lst

    I know about editing boot arguments at boot screen and I just removed all 'save-mode' options from menu.lst but everytime I build a new kernel, today 2.6.30.9, all 'old save-mode' options are added again. And there is no line in menu.lst with these options. So I don't know where they come from...
    When I got a kernel update from the official repos the same happend.

    Try checking in /etc/sysconfig/bootloader - it sounds like suseconfig
    might be getting run, and that would cause it to pull the options in from
    YaST if you're just modifying the menu.lst file.

    I could tell you how to permanently remove them, but I won't, because those options are there for a very good reason.

    Failsafe entries are for troubleshooting, _if_ you run into a problem i.e. with ACPI, you will be glad they are already there.

    Yeah, editing /etc/sysconfig/bootloader fixed it. Thanks!
