How to install realtime kernel on Ubuntu Live USB - Ask Ubuntu


i using ubuntu live usb stick 16.04.1 boot toram , persistence option. far best sounding setup audio streaming (firefox+adobeflash+tidal). best setup in terms of usability , user experience. me far better volumio 2 , daphile in regard. ubuntu live usb uses generic kernel. try out realtime kernel. not want install ubuntu. want ubuntu live usb realtime kernel. how can that?

installing new kernel straightforward, using problem. default kernel in use time can start doing interesting. new isos have filesystem iso9660, cannot modify them (like putting in new kernel). easy workaround possible uefi machines using grub boot -- put fat32 filesystem on target, , copy contents of iso there. modify grub boot command eliminate preseed business (because fat filesystem cannot have "ubuntu" link).

just copying files iso fat filesystem, result in working uefi boot, missing link capability results in kernel arguments "file="/cdrom/preseed/..." not name existing files. replace /cdrom... below after boot=casper item:

persistent live-media-path=/casper/ ignore_uuid

try existing kernel first, replace new one.
