It might not be worth it. One of the reasons for it is that mkfs.ext4 can be set up to try to pull in libmagic using dlopen, to minimize the package dependencies for things like the distribution's installer or minimal root setu[s for Docker, et. al. As a result, mkfs.ext4's ability a pre-existing foreign fil;e system won't always work, depending on the libmagic shared libraery is available. It will be a lot easier to add a test for this functionality functionality in e2fsprogs's regression tests, since the build system will know whether libmagic is available. So maybe it's not worth trying to teach generic/740 how to test mkfs.ext4, at least for now. Cheers, - Ted
