I mean, this is not a frequent operation, so we could ignore the overhead of
fork + exec. So yes, I would accept that. If we find something more efficient
it could always get replaced by that transparently any way.

Actually, I requested the feature to be able to add one through the storage
add and update API/web-interface a long time ago from Alwin, was lost in the

So; I do not see that as issue but rather as another small feature we could
Handling in the backend should be similar to other secrets, e.g., pbs password
