u-boot is used for the partition/slot switching only.
This is sufficient for basic functionality of of RAUC.

In the status file we store some additional information, like when and how often
a slot was updated, or which bundle version it is running.
You get this for example when running "rauc status --detailed".

Sounds interesting, but I cannot tell because I don't know what you did to untar
;)
But actually there is no magic. We simply call 'tar' to unpack. Maybe you've
used a slower (de)compression algorithm when testing manually?
