I started implementing this, but adding clientUid/Gid as a attribute
(property) of 'LocalStore' feels wrong. The LocalStore is about the
store: files being there, querying and such. Even "build" is a bit of a
misfit IMO.

Okay, probably you mean, passing to the ‘LocalStore’ constructor and
then forward them to the goals. Which means changing
`makeDerevationGoal', which is used quite some time. From there you
would need to pass it onto the 'DerivationGoal' constructor. These are
quite some changes for the rare case of building, and only if the build
failed and only if the user passed --keep-failed.

I have the impression, that 'Settings' have been introduced exactly to
save passing around such information. "keep-failed" is passed to
'deleteTmpDir()' exactly this way (via Settings). Which means if passing
clientUid/Gid via constructors,  we would have two different ways of
passing information used in the same small function - which would be
inconsistent.

Thus said, I'm in strong favour of using Settings.
