I was expecting the use of non-SSH git remotes without network access. Any mounted file system can be a valid remote such as a USB drive. I use file-based remote to keep some repos encrypted on S3 using Rclone.

For example, `git remote -v` would show: `secure-s3 /mnt/fuse/rclone/secure-s3/git/$REPO.git`

I think concurrency is a problem with file-based remotes but for one person keeping a desktop and laptop in sync it is much simpler than running a VPS.
