Good that you are bringing this up. So I think what we should do here is
bringing back XZ compression with -8 so that we do not waste too much space w=
hen
extracting the image again.

To not run into memory limits we should detect how much memory the build host
has and set the memory limit to maybe 80% of that. xz will then automatically
scale down to a number of parallel processes that it can fit into memory.

We will at least need about half a GB which should be a sensible requirement =
for
a build system any ways.

Will you work on this bringing it into the build system?!
