Uh, I meant: it=E2=80=99s great news that the MOOC on reproducible research=
 will
be talking about Guix.

I see.

Yeah, that=E2=80=99s what they are, so maybe it=E2=80=99s simpler to presen=
t profiles as
persistent environments.

What would you suggest?  =E2=80=9Cguix log=E2=80=9D, =E2=80=9Cguix roll-bac=
k=E2=80=9D?

Thanks,
