> Until now, using any package transformation would disable the automatic
> GC root creation and caching in ‘guix shell’. This change introduces a
> finer-grain distinction: a command like:
>
> guix shell --tune inkscape
>
> is now subject to caching, whereas:
>
> guix shell --with-latest=inkscape inkscape
>
> remains non-cacheable.
>
> * guix/transformations.scm (%transformations-with-external-dependencies):
> New variable.
> (cacheable-transformation-option-key?): New procedure.
> * guix/scripts/shell.scm (profile-cached-gc-root): In the
> ‘transformation-option-key?’ clause, call ‘loop’ when
> ‘cacheable-transformation-option-key?’ returns true.
