Public bug reported:

Install randomely crashes/fails/hangs on systems with 3GB or less
When the system doesn't hang, I can see kernel OOM killing random processes like calamares, cryptsetup etc.

I had ~75% success of installing Kubuntu 24.04 daily on VMs with less then 3GB and almost 0% on 2GB VMs.
Previous livecd installers had no issues with 2GB VMs and

Once the system is installed it functions satisfactory with 2GB.

I believe adding zram-config to livefs/casper would allow installation
on systems with only 2GB of RAM.

Note,
Similar issue also affects other Ubuntu images so the issue is not calamares specific.
The problem first appeared around the time of switching to Kernel 6.8.
I believe the issue is overlayfs related since that's the main difference between livefs and installed system and there were a lot of changes related to overlayfs.
