To simplify things later, could #:user "ipfs" and #:group "ipfs" be
added to the least-authority wrapper (and implemented in the 'least-
authority procedre)? Then ...

would become simpler as it wouldn't need to fork, exec, waitpid and
dynamic-wind. Alternatively, if associating a user and group with a
pola wrapper is problematic (*), what do you think of defining a
'system*/with-capabilities' or 'invoke/with-capabilities' in a central
location?
Greetings,
Maxime.
