There was a problem hiding this comment.
I can confirm this fixes it, however not directly for the reason we assumed ($out). Consider this:
nix-build -E 'with import ./. {}; vmTools.runInLinuxVM (hello.overrideAttrs { __structuredAttrs = false; preVM = "exit 1"; })'
This is without structuredAttrs and will fail as expected.
But, before this PR:
nix-build -E 'with import ./. {}; vmTools.runInLinuxVM (hello.overrideAttrs { __structuredAttrs = true; preVM = "exit 1"; })'
The same with structuredAttrs will not fail - because $preVM is not even set. Thus, it will just happily proceed.
After this PR, this will fail as expected.
Thus, you might want to adjust the commit message slightly.
This is required for `preVM` which can be arbitrary code: e.g. `vmTools.createEmptyImage` assumes the presence of `$out` in its default configuration. Also, before this patch, `preVM` wasn't even set in the `__structuredAttrs` case.

When this is used, the existance of
$outis assumed, however this is not the case for structured attrs. This PR adds that.Also, an obsolete, broken
