When manually executing the second 'remote-assertion.scm' file, the one
containing the 'find-partition-by-uuid-bit', it hangs indefinitely, I 
have
attached it's strace to this email.

Note that doing a “guix system reconfigure” on the deploy target with a
config file containing using “(device (uuid ...))“ work, it's only when
using “guix deploy“ that this issue manifest itself.
