In 9ac1ab10c963a86457c2c9b1edf31542ff3737cd this library function was refactored to use mkfs.ext4 instead of cptofs. There are two problems: If populateImageCommands would create no files (which is fine), a cp invocation would fail due to missing source arguments. Another problem is that mkfs.ext4 relies on fakeroot to have sane uid/gids in the generated filesystem image. This currently doesn't work for cross compiling.
