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 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.
