Hi, I'm wondering how dangerous the interaction of git with the unison file synchronizer[1] can be. Another way of asking the question can be: what's the best way to keep two machines with many git repositories in sync? Unison is a userland application that does bi-directional synchronization of two directories. Typically, to keep a laptop and a desktop synchronized (modify a file on the desktop and another on the laptop, unison will copy the files). I find it very usefull to keep large directories containing unrelated projects (typically, ~/teaching/, ~/research, ..., my colleagues even synchronize $HOME on their laptops) in sync between two machines. Actually, git achives something similar (and lot more, of course): modify a file here, commit, modify another there, commit, and then push & pull can do the sync. I find git excellent to manage somehow self-contained projects (~/teaching/2007-2008/whatever-course/), but inappropriate for $HOME or such big containers (need to run more commands, disk-space overhead, ...). So, at the moment, I have both unison and git. My fear is that unison touches the content of the .git/ directories. So, for example, if I commit on one side, and commit something else on the other side, I'll get unison conflicts at least on .git/refs/heads/master and .git/index, and resolving the conflict in favor of either side leads to dangling objects whith important content. What I'm doing right now is that I try to make sure I don't run unison when trees have diverged, which is not really satisfactory since 1) I can be wrong, and a miss-synchronization could lead to data-loss, and 2) that means not really taking advantage of unison. What about you? What do you use to synchronize your laptop and desktop, or home and office? Anybody using unison and git on the same filesystem?
