I want to ask how to create an ISO, my OS is made with LFS 11.0 System V and I install it in Qemu. My Host OS is CAELinux.

The main concern is:

Is it possible to move the LFS OS installed in Qemu to replace my Host OS?
or should I just do LFS from zero toward my Host OS? 

Here are my conditions:

  • I do not use package manager
  • PinguinEggs package can't be used to create ISO for my OS.
  • I use Rsync to copy all files and symlinks from my LFS OS, but the problem is I do not know whether to delete all files in my CAELinux then Rsync all files from my LFS OS replacing the deleted CAELinux system files
  • I have 2 SSD, one is for CAELinux, the other is still 95% free and already used to store the LFS OS I created through Rsync , do you think it is better to create dual boot? CAELinux + my LFS OS? Or just replace the CAELinux with my LFS OS?

Tell me if there is another better solution for this. I want to test my OS in the real hardware. The reason I want to create ISO is because I can install it in another PC/laptop.

Attached pictures:

  1. The mounting Qcow' partition containing the main partition of my LFS OS (/usr /var /opt ..) The problem is there are more partitions from creating OS (nbd0p1 nbd0p2 nbd0p3 ..) How to create ISO or install this LFS OS to any hardware/laptop? Not just my current laptop because in the future hardware replacement / upgrading is inevitable.


  1. The mkisofs contain a lot of warnings: too many level of symbolic links (is it really going to work or should I just do LFS from zero toward my Host OS? ) mkisofs

  2. Using RSync works but I do not know how to proceed from this stage either to replace the host OS by my LFS OS or to create dual boot. Partition in LFS OS The LFS OS in Qemu and the backup files in my Host OS
