I don't see any obvious problems with the patch, though I haven't tested.

It would be easier to review if you modified one or two packages
and services in guix itself to use this wrap-in-search-paths procedure
though. (Preferably services with a system test in gnu/tests/*.scm.)
Otherwise, guix would have a procedure that is not called from anywhere
and isn't tested either, which is a bit of a hard sell.

Not sure how this helps with

, but this seems useful for shepherd services (as you mentioned).
