Subject: Add ostree_ensure_repo_writable()
X-Git-Tag: archive/raspbian/2022.1-3+rpi1~1^2~831
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=7941189dfde3795fb649aba41e207f0072dfcd86;p=ostree.git

Add ostree_ensure_repo_writable()

Commands that need to write files within the repo directory can call
this early to ensure the directory is writable for the current user.
If not, it fails with a helpful "You need to be root to perform this
command" message.
