A quick look at the docs seems to indicate that we'd need to do

git pull
git submodule update

which doesn't look like a win over darcs-all. Also, I completely fail to understand what git submodule update does. It doesn't seem to pull all patches from the master repo. The git submodule docs are even worse than the rest of the git docs which is rather discouraging.

Thomas says that it doesn't do automatic dependency tracking which looks like a huge weakness to me. Personally, I haven't been able to successfully unpull non-consecutive chunks of patches with git so far but I only tried 2 or 3 times before giving up.
