Re: about live-boot with uuid

["alter.md" <alter.md@free.fr>]

    Just a comment about it :
    
    After every change of an uuid, in every table, fstab and grub conf,
    the content , has to be regenerated with the new uuid.
    
    Be very carfull after a  command as "dd" if you want  duplicate the
    first hd on a second one (IE, if = /dev/sda for="" ...),
    there's the same uuid after that on every HD .
    Your system can't know in wich  Hd of them he has to copy new files,
    or wich swapfile to use, etc ... And you can loose every masterboot
    and not only datas, especially with UEFI.
    So you had to unplug the target after a DD , booting-it separatly
    and regenerate every table on it, just before rebooting again.
    
    Good luck for you

I hope this email finds you well, I am using live-boot in my project but I am try to setup live-media with uuid to fix issue live boot mount wrong filesystem squash file if I have 2 bootable disk available and both use live-boot and same file structure on it. 

This first I am try is to use set live-media=/dev/disk/by-uuid/XXXXXXXX. it failed because persistence media and live media are the same so it already mount by persistence, so where_is_mounted not find the mountpoint by device(/dev/sdX). so it can be fix by a small change, for detail can be see here: https://bugs.launchpad.net/ubuntukylin/+bug/1992195

Then after few days I found some people use live-media=UUID=XXXXXXXXX, but I can't make it works.

Does anyone can help me fix this problem? Is anything I miss in the 2nd way, or anyone can help me take a look the bug I put when I try the first way.

Thanks
