During the last test where we could run vaults an ARM package was supplied. I just extracted that package and ran the vault on my pi3. It ran just fine, never crashed or anything.
So I guess it’s easy as that or perhaps that is not what you mean?
The network for TEST 8 has been taken offline though so not sure what you could do with the package now. I guess you should wait for the next test where user vaults are enabled.
