git-annex/doc/bugs/safe.bareRepository_breaks_git-annex_uuid.mdwn

Turns out that git-annex breaks badly when git is configured with
`safe.bareRepository = explicit`.

The breakage starts with git-annex init:

	joey@darkstar:~/tmp>git init g
	Initialized empty Git repository in /home/joey/tmp/g/.git/
	joey@darkstar:~/tmp>cd g
	joey@darkstar:~/tmp/g>git-annex init
	init  ok
	(recording state in git...)
	joey@darkstar:~/tmp/g>git show git-annex | tail
	+ joey@darkstar:~/tmp/g timestamp=1688579729.946567508s

uuid.log has a NoUUID item logged to it. This is despite annex.uuid being set.

This is because git-annex runs `git config --list`
inside `.git`.. Which with that config set, omits looking at
`config` because it thinks it's in a bare repository.

Fix breakage when git is configured with safe.bareRepository = explicit Running git config --list inside .git then fails, so better to only do that when --git-dir was specified explicitly. Otherwise, when the repository is not bare, run the command inside the working tree. Also make init detect when the uuid it just set cannot be read and fail with an error, in case git changes something that breaks this later. I still don't actually understand why git-annex add/assist -J2 was affected but -J1 was not. But I did show that it was skipping writing to the location log, because the uuid was NoUUID.
