Subject: git-init-db: initialize shared repositories with --shared
X-Git-Tag: v1.1.0~26
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=af6e277c5eddbcf82582b4bbd3e50b36aa61a20a;p=git.git

git-init-db: initialize shared repositories with --shared

Now you can say

	git-init-db --shared

if you want other users to be able to push into that repository.

[jc: info/ and objects/info/ need to be group writable if the
 repository is shared --- otherwise packs and refs files cannot
 be updated.]
