Fail-fast if file access permissions for out and status prevent an update
Regular backups of the out and status folders for an Onionoo server is encouraged. When running as a separate user it wouldn't be uncommon to have the archives owned by another user. Onionoo's updater doesn't check the access permissions for out and status until after rebuilding the folder in, and it basically fills the logs with entries for every file it failed to access. So if you didn't recursively set access permissions that's a lot of log entries before the updater finally stops.
If the Onionoo updater were to check the permissions early and fail-fast it would prevent this behavior.
