For example, my bash wrapper that starts the VM could inspect the image file and decide which VM is appropriate (spur, non-spur, 32-it, 64-bit, etc.) Otherwise the user needs to guess and decipher cryptic error messages. Has anybody made such a "DWIM" script that automatically selects the right VM? Would love a link to use for reference. Is there any compatibility matrix to help me understand which VMs are compatible with which images? Now I know that the 64-bit VM can't run 32-bit images but I am wondering whether e.g. the Spur VM can run older images like Pharo 4 / DrGeo / etc or whether different VMs need to be built for those too.

I don't think it's reasonable to expect end-users to edit /etc files in order to run GUI applications. I also don't like applications blindly printing instructions that are distro-specific (there is no /etc/security directory on NixOS for example.) I also :-) don't immediately see why it is safe to assume that running pharo at realtime scheduler priority is what the user will want when their system becomes overloaded. I already know that another problem coming down the pipeline, after making the VM work, is finding hard-coded paths in popular image files that only work on some distributions. For example the Moose image makes some unsafe assumptions about what libcairo will be called, https://github.com/NixOS/nixpkgs/pull/14414 Grumble, grumble, grumble :). But soon all fixed!
