For what it's worth, here's an anecdote about this: I work on some open source software which includes a web-based repository browser for Git, somewhat similar to gitweb. We implement this partially by executing `git` commands from the webserver (usually Apache). For example, we run `git cat-file …` to retrieve file content to show to the user. After this change, a number of users who manage installs of the software are hitting "fatal: unable to access '/root/.config/git/config': Permission denied" while browsing repositories, because their Apache runs as some unprivileged user (like "apache" or "www-data") but with HOME=/root. We've seen about half a dozen reports of this now, so I believe this sort of setup is at least somewhat common and not just a bizarre one-off user with a broken environment. Users generally have difficulty resolving this error on their own, as it's not obvious that this boils down to an Apache environmental issue. We'll likely resolve this by running `HOME=/ git ...` instead of `git ...` when we execute commands (or some more finessed version of that, but basically pointing HOME at some dummy readable directory). From cursory investigation, it appears we can't avoid this fatal with more surgical settings like GIT_CONFIG or XDG_CONFIG_HOME, since git still ends up looking in HOME and fataling anyway. This fix is a bit clunky, but not really a big deal. I imagine our use case is fairly unusual, but I wanted to relate it in case it's helpful in balancing concerns here. If I've missed a more reasonable approach to solving this than redirecting HOME, please let me know, but it looks like that's more or less what the git-daemon patch is doing too.
