Hello Natanael,

Very interesting!
Can you tell something more about the metadata, how is it stored in a RAM based 
system? Is it recreated every time the system boots? How much memory does this 
metedata take, both running and storage.

Also note that there are a lot of lrp packages, could or is this system 
backwards compatible with the existing packages?
