gaf is the new gokrazy archive format output type.
It is immagined for storage and upgrade.
A single, uncompressed zip archive files that contains:
- the MBR image (mbr.img)
- the boot image (boot.img)
- the root image (root.img)
- the SBOM of the gokrazy build (sbom.json)
It is lighter in size than a "full" disk image (it doesn't have the
partition filling bits).
It contains all the necessary bits to upgrade a gokrazy instance (all it
takes is the 3 imgs).
It can be directly accessed for a single file extraction (non compressed
zip property).
It can be easily unarchived by gokrazy appliances (cheap unzipping).
It is easy to verify what the build contains (SBOM alongside to be read).
