[bug#46215] [PATCH] Add yadm

[Ellis Kenyő]

I don't think you're understanding my question.

A number of the dependencies are optional, for example some of the 
jinja template commands.

When this builds, if those packages aren't installed before you 
install yadm, the path gets set to `#f`.

If you then later install them (one of them for example is a 
python module so likely wouldn't be installed through guix), the 
path in yadm is still `#f` so it would never find them.

Do I have to also package everything it has a soft dependency on?
