Are you imagining a file move to have some sort of atomic guarantee?
Even if /tmp and the repos are both on local storage, if they are on
separate volumes (a common case), a move becomes a copy/delete
operation which might have fewer guarantees than you are perhaps
expecting.

Feel free to ignore this if I'm just misunderstanding what you are
saying.
