For some time I have been curious to see how successful creating ISO and SFS images would be when working from a KLV Pseudo Full Install running in a QEMU virtual machine. If working with virtual HDD's would still create accurate file system images.
This method is fully manual and requires creativity. @fredx181 's remaster utility will most likely do the same job and is far less complicated to use.
Note: I am using Tigervnc-client to connect to the VM
The test entails using KLV-Airdale-rc4.1.iso booted with QEMU. First steps are creating the VM using the aqemu wizard to set up a basic VM with 4 gb of RAM and these extra arguments in the Advance Options -cpu host -vnc 192.168.254.13:0
which selects using the CPU from the host machine and setting up the VNC feed so it is accessible from any machine on the LAN using a VNC client. Not that important but allows working on the QEMU machine from a remote host.
In aqemu
added in the Media section the ISO for rc4.1 as a CD-ROM drive. I immediatley used the aqemu option to generate a start script for the virtual machine. Now ready for a first system start, by executing the KLV VM start script and the Tigervnc-client and the boot selection menu appears, from which I selected RAM0 mode. At this point the VM HDD has no partitions and is not formatted so RAM0 mode is perfect for this point of the project.
