I understand. Especially on the light of…

…this. I agree that the aim is the guarantee of a preservation for
revisions only reachable by “guix pull”.
Aside PoG, this raises a point that I asked elsewhere. The time-machine
is able to go any revisions, but 1. some revisions are known to fail and
2. only some revisions are preserved. Therefore, something appears to
me missing: advertise about this collection of “working” revisions.
*working still a vague meaning. :-)
Well, I do not know via which mechanism? Maybe add something as narinfo
or else attached to this collection of “working” revisions. Then,
guix time-machine --commit=1234abcd -- help
would warn that this 1234abcd is not part of this collection and there
is no guarantee it would work.
I do not know, I am thinking loud. :-)

I understand and I agree.
