Right.

Indeed.

If you look at nix-daemon.cc:543, there’s currently no way for a client
to say “default value.” The only way for a client to get the daemon’s
default values is to not call the ‘set-build-options’ RPC at all; it’s
all or nothing.
I think the way forward would be to add a new RPC, say
‘set-build-options2’, that would take a list of key/value pairs, where
keys are option names. Options not mentioned in a ‘set-build-options2’
call would keep their default value.
How does that sound?
Thanks,
Ludo’.
