It=E2=80=99s OK for packages of up to several MiB (the vast majority of packages), but here we=E2=80=99re talking about 3 GiB. Grafting is intentionally not substitutable, on the grounds that it=E2=80= =99s quite fast for most packages, and certainly faster than re-downloading stuff. TeX Live is obviously an exception. I=E2=80=99m not sure how to address it= . We must make grafting faster but even then, it=E2=80=99ll probably never be le= ss than 10mn for something this big. Thoughts? Ludo=E2=80=99.
