Sure, this is reasonable.

I am indeed using debci images to ensure reproducibility. So the software environment should be the same.

Just more observations here:

- If I limit the test file size to 1G, quite many tests would fail even with adequate resources.
- If I try to skip large_files as you indicated with 2G memory, the tests could proceed for a bit longer,
  but still got hang on some later tests. Since there are so many tests and I am not familiar with most of them,
  I have to try it repeatedly to find out which to filter out. Even I could do so, some (other, not seen before)
  tests would fail unexpectedly. These problems might be hard to workaround.
- With my fixes to dependencies, the tests could run to the ending without errors on 2 core + 8 GB.

Therefore I think trying to fit zfs-tests into a normal debci VM might be troublesome.
