Input images used with mender-convert are virtually always compressed. Today the user is required to decompress the image first, which is a usability issue we can easily improve by supporting compressed input.
Secondly, the output image should be compressed with the same compression format as the input as well. This way, the user can follow exactly the getting started guide from the board manufacturer (and not have to fail and translate the decompression commands / steps because he is using mender-converted images).
- mender-convert supports compressed input in at least these formats: .gz, .xz, .zip
- when compressed input is given, the output is compressed with the same format
- it is possible to specify the output compression format
- .gz is the default output compression format if neither the input is compressed nor the output compression format is specified
