Hi, I've seen in Ludo's slides that speeding up guix pull is topic. Here is a random idea on the: "git pull" can probably be speed up by using something like git init . git remote add … git fetch --depth=1 origin master git checkout FETCH_HEAD This will only download the top-most commit resp. commit-state. From my mostly up-t-date clone, this method downloads only 1559 objects and 'du -s .git' reports 13M – compared to "git pull" downloading 133284 objects and taking 49M. We could use this for downloading sourcce-code via git (git-download). -- Regards Hartmut Goebel | Hartmut Goebel | h.goebel@crazy-compilers.com | | www.crazy-compilers.com | compilers which you thought are impossible |
