How did you instantiate the profile? Using a manifest file? Did the
profile use only one Guix commit or several?
How aggressive it was? What did you run?

Interesting whislist.

Currently, the easiest way to protect the state of a profile is to
write down a manifest file, IMHO.
If this manifest file track the Guix commit and the targeted packages,
then you can re-instantiate this very profile whereever and whenever
you want to.


Hope that helps.

All the best,
