More check are also done about the file system states: - traverses a symlink (e.g. a/symlink_here/b) - inside a nested repository (a callback can be used to approve some nested repositories, e.g., subrepositories) The file system checks are only done when 'realfs' is set to True (the default). They should be disable then we are auditing path for operation on stored history. If 'cached' is set to True, audited paths and sub-directories are cached. Be careful to not keep the cache of unmanaged directories for long because audited paths may be replaced with symlinks.
