Thread: Change kernel boot parameters at livecd iso.

  1. #1

    Default Change kernel boot parameters at livecd iso.

    I need to add 'toram' boot parameter at livecd iso. Not during boot (not manually). But as part of string in isolinux.cfg. How can I do it in SuseStudio? Custom scripts applied to the appliance, before making iso. So I can change boot parameters into /etc/default/grub, but can't in '/boot/x86_64/loader/isolinux.cfg'

    Or how can I modify ISO image (add parameter into isolinux.cfg manually) and keep ISO bootable?

    I tried genisoimage, xorriso, mkisofs ... and images had been unbootable (after I unpack-change-pack it again)

    I think you can edit the /boot/grub/loopback.cfg file (when you made the stick with usb-creator) or the /syslinux.cfg file (when you used unetbootin) on the USB stick to include this.

    I would actually also want to know this..

    I have overlay files to big for the defailt ramdisk_size leading to boot
    failure of an ISO image; if you
    change the ramdisk_size manually at boot it works but it would be nice
    to specify a different default.

    Please start your new subject in a new thread, with a title that has keywords about your question/problem.
    That is the best way to draw the attention of people. Not all will go and look at the end of old threads, but many will browse through the titles of new threads to see if they can help.
