Another option is to rely on the ‘time-machine’ and ‘shell’ LRU caches.
That is, you can run:

  guix time-machine -C channels.scm -- shell -m manifest.scm

Both tools cache their result, with a GC root (similar to what you would
do with ‘--root’), and reuse it (similar to ‘--profile’).  These two GC
roots may be removed if you’ve not touched them for some time, at which
point ‘guix gc’ can potentially remove these profiles.

Would it work for you?

I’m more comfortable recommending this than asking people to manually
manage cached profiles and GC roots.

Thanks,
Ludo’.
