You can also tell git that the .git dir is completely separated from the working dir:

    alias dogit='GIT_WORK_TREE=/path/to/src/dir GIT_DIR=/path/to/dotgit/dir git'
    dogit pull remote treeish

I set this up as a "poor man's version control" on a large client's server back in 2016-ish. I was lost for words when last year I saw my colleagues still using Ctrl-R to rerun that alias line.

Yes, that's roughtly what I am doing in my post-receive hook:

    export GIT_DIR=/path/repo
    export GIT_WORK_TREE=/path/working-directory
    git checkout -f
