I could miss a point. In 3-5 years, some people will be still running Debian stable (or maybe oldstable or maybe this stable is LTS), so they will =E2=80=9Capt install guix=E2=80=9D at 1.2.0, right? But then there is= no guarantee that Berlin will still serve this 5 years old binary substitutes. But =E2=80=9Cguix install=E2=80=9D fallback by compiling what is missing, right= ? Then the question will be: are the upstream sources still available? Assuming that SWH is still alive at this future, all the git-fetch packages will have their source, whatever the upstream status. For all the other methods, there is no guarantee. On the other hand, at this 3-5 years future, after =E2=80=9Capt install gui= x=E2=80=9D, people will not do =E2=80=9Cguix install=E2=80=9D but instead they should d= o =E2=80=9Cguix pull=E2=80=9D. Therefore, the compression of substitutes does not matter t= hat much, right? The only strong backward compatibility seems between =E2=80=9Cguix pull=E2= =80=9D rather than all the substitutes themselves. Isn=E2=80=99t it? Other said, at lea= st keep all the necessary to have =E2=80=9Cguix pull=E2=80=9D at 1.2.0 be able= to complete. Thanks for this opportunity to think at such time scale. :-) Cheers, simon
