TBH I do not see any other activity of @josh-bartel on GitHub, maybe we can commit and add tags ourselves? @lorc WDYT?

[lorc]

@klogg, I can add Reviewed-by tags, no problem. But I can't add Signed-off-by

Hi @josh-bartel,

Change this:

repo_args.append(>>>f<<<"--git-lfs")

into this:

repo_args.append("--git-lfs")

in order to fix the following flake8 finding:

Run # stop the build if there are Python syntax errors or undefined names

./build/lib/moulin/fetchers/repo.py:67:30: F541 f-string is missing placeholders
./moulin/fetchers/repo.py:67:30: F541 f-string is missing placeholders
2     F541 f-string is missing placeholders

I pushed a new change to address this.
