I think this is a good idea. I had a look at the code and I don't see anything against adding a --simulate/--dry-run option that is not producing any tarball or directory but only checks the given variant in combination with --include. Of course hooks would not be executed during --simulate/--dry-run. Unfortunately, I think it would be quite complex to implement this new option properly due to the spaghetti-nature of the codebase. A lot of care has to be taken to make the option work in any mode, variant, with --include and with all the possible output options where mmdebstrap filters through tar, gzip or tar2sqfs. So a lot of new testcases have to be added for that as well. Since this is a bit more work, I will postpone this to later or wait for somebody to write up a patch. :) Thanks! cheers, josch
