During the Gitea 1.22.1 upgrade we had failures because gitea wanted to
write back to its app.ini config file and couldn't do so due to file
permissions. We address that by fixing the formatting for one entry in
the template then separately update a secret var to match what ended up
being deployed to gitea09. In theory this should make everything line up
such that we don't actually need to write back to the file at all.
If this continues to fail we will instead update file permissions and
let gitea rewrite its file instead. But that would be the next thing to
try.
