Description
I just forked https://data.dev.neuropoly.org/neuropoly/spine-generic-single -> https://data.dev.neuropoly.org/kousu/spine-generic-single.
Server side, this caused a local clone:
gitea@data:~/data/gitea-repositories$ cd kousu/spine-generic-single.git/
gitea@data:~/data/gitea-repositories/kousu/spine-generic-single.git$ git remote -v
origin /srv/gitea/data/gitea-repositories/neuropoly/spine-generic-single.git (fetch)
origin /srv/gitea/data/gitea-repositories/neuropoly/spine-generic-single.git (push)
and per git-clone(1)
-l, --local When the repository to clone from is on a local machine, this flag bypasses the normal "Git aware" transport mechanism and clones the repository by making a copy of HEAD and everything under objects and refs directories. The files under .git/objects/ directory are hardlinked to save space when possible. If the repository is specified as a local path (e.g., /path/to/repo), this is the default, and --local is essentially a no-op.

And to make doubly sure, here's looking one up by it's actual inode number:

But the repo sizes are wildly different: ~885MB vs ~1.5MB:
And this is of course because it didn't clone the annex files:
gitea@data:~/data/gitea-repositories$ ls kousu/spine-generic-single.git/annex
ls: impossible d'accéder à 'kousu/spine-generic-single.git/annex': Aucun fichier ou dossier de ce type
and of course this means the repo is broken

So, we need to add calling git annex get to the Gitea "Fork" button -- but only in git-annex repos, of course.
However, if we can, we should try to use hardlinks the way git clone does, as the git annex get I ran above actually made copies
