As proposed, somehow, in [1], I think we have nothing to loose with optionally =E2=80=9Cdouble hashing=E2=80=9D (or even triple or more). I do= not understand your concerns in [1] and I will discuss overthere. :-) About =E2=80=99svn-multi-fetch=E2=80=99 and TeX, what is at our advantage i= s that most TeX Live packages use =E2=80=99svn-multi-fetch=E2=80=99 via =E2=80=99simple= -texlive-package=E2=80=99 relying on =E2=80=99texlive-origin=E2=80=99. And from official TeX documen= tation [2], Subversion is not the recommended access, instead they suggest to rely on =E2=80=99rsync=E2=80=99. Moreover, some Git mirror is available. Therefore, about TeX we could ask if relying on Subversion is still the =E2=80=9Cgood=E2=80=9D way and maybe we could switch to something else as u= rl-fetch or git-fetch. Hum?! Not convinced by my proposal here. :-) Well, IMHO, there is 2 issues: one about using SWH as fallback for packages using svn-fetch and another one about TeX Live packages. It could be nice to solve them both at once but maybe we should start now one foot, now the other. 1: https://yhetil.org/guix/87jzzxd7z8.fsf@gmail.com 2: https://tug.org/texlive/svn/ Cheers, simon
