There was a problem hiding this comment.
A detail: I would use == instead of !=, it's slightly easier to read. Something like:

dfseems to treat passing0using an env var the same way as passing an invalid value, by using the default block size instead. SoDF_BLOCK_SIZE=0andDF_BLOCK_SIZE=invalidare functionally equivalent (including the cases involving the hierarchy of env vars).
