What =E2=80=98guix=E2=80=99 is trying to tell us is that
5b7a1cb077931a020c0b7e3b12f12a7bda221d96 is not a =E2=80=9Ccommit=E2=80=9D =
object: it=E2=80=99s
a =E2=80=9Ctag=E2=80=9D (or =E2=80=9Cannotated tag=E2=80=9D) object.

Instead, you should run:

  guix time-machine --commit=3Dd68de958b60426798ed62797ff7c96c327a672ac -- \
    build hello=20

=E2=80=A6 where d68de958b60426798ed62797ff7c96c327a672ac is the commit this=
 tag
points to (v1.0.1).

That said, as a user, one certainly doesn=E2=80=99t care about this subtlet=
y.
It would be nice if (guix git) could automatically dereference annotated
tags, though it doesn=E2=80=99t seem to be that simple (there are places wh=
ere
we explicitly ask for a commit object and we need to keep some sort of
=E2=80=9Ctype checks=E2=80=9D on Git objects).

Thanks,
Ludo=E2=80=99.
