Hello,

swedebugia <swedebugia@riseup.net> skribis:

> Trying to get an updated an old GuixSD installation via guix pull on a pr=
e 0.10 GuixSD returned an error message about gexp-modules not found. (deta=
ils can be provided if asked).=20

Could you post the full backtrace?

> I suggest we either test pulling from old versions (and fix errors) or ma=
ke it clear in the manual that pulling from very old GuixSD (older than 0.1=
2?) is not supported.

Pulling from a very old Guix may not work.  We try hard to keep things
running, but the old =E2=80=98guix pull=E2=80=99 had defects, plus the file
build-aux/build-self.scm (which =E2=80=98guix pull=E2=80=99 runs) might use=
 features not
found in very old versions.

I agree.

Thanks,
