[Vm-dev] Re: [squeak-dev] Linux VM can't read files from /proc

[Alexander Lazarević]

Ah, you're right. The Squeak VM gets the file size via stat and does not
just read the contents from the file. So for squeak the file looks just
empty.
That's a shame because /proc/self/environ would be an easy way to access the
environment variables from within the image without any need to add a
specific primitive to the VM or use FFI.
