This is a question I had but not reported when commenting elsewhere this
patch.  I was thinking to suggest:

    (module-ref (resolve-interface '(gnu packages certs)) 'nss-certs)

which lazily loads, IIUC.  Then I gave a look to Guile manual which
mentions:

     ‘#:autoload MODULE SYMBOL-LIST’
[...]
          An autoload is a good way to put off loading a big module
          until it’s really needed, for instance for faster startup or
          if it will only be needed in certain circumstances.

Therefore, could you explain the difference if there is one?



Cheers,
simon
