Would it be possible to have the option of using an existing python installation? I have project-specific conda environments, so it would be great if I could set which Python should be used.
That's good to know. Still, I think it would be much saner if Unison was self-compatible at least within the same major-version. It's an excellent program, beyond the tricky details of setting it up on all your systems.
Does unison still have the problem that it refuses to work unless the exact same version of the program is installed on every computer? Also, I've found it extremely hard to install on linux boxes where I do not have root access.
