Okay, this is helpful. It appears to me that with GIT, you have to have more faith that everything will work correctly. With wget, you get a chance to do the upgrade a little more slowly and in pieces. Maybe GIT would be more appropriate when the updates are within the same "point" number (2.4.1, 2.4.2, 2.4,3). wget might be better when moving between major point upgrades (2.4, 2.5, 2.6).
I don't understand the "firewall" comment. What does this do?
Thanks.
