When running on NixOS, I faced an issue.
The initial mirror operation worked, but subsequent syncs fail with the error:

Error message: Failed to sync repository: Snapshot failed; sync blocked to protect history. git command failed: fatal: Unable to create '/tmp/gitea-mirror-backup-g9VYmK/repo.git/data/repo-backups/u5wbKMuhe95WV9fXH3y0DOcD4IX04B27/<OWNER_REDACTED>/<REPO_REDACTED>/2026-03-01T02-19-08-257Z.bundle.lock': No such file or directory

At first, I thought it was a permissions issue, but adding ReadWritePaths = [ "/tmp" ]; didn't change anything. Then I looked at the code, and I got a feeling that there's something wrong with the path construction. I feel like /tmp/gitea-mirror-backup-g9VYmK/repo.git is one part, and /data/repo-backups/u5wbKMuhe95WV9fXH3y0DOcD4IX04B27/<OWNER_REDACTED>/<REPO_REDACTED>/2026-03-01T02-19-08-257Z.bundle.lock is something different, but somehow they got joined into one. 🤔

It doesn't happen all the time, but some repos/branches synchronize sometimes. I can't find a pattern yet.

Fixed in #204 — the bundle path was being passed as relative to git -C, so git resolved it against the temp clone dir instead of the actual backup directory. Swapped to path.resolve() to always guarantee an absolute path. Shipped in v3.10.1.
