the shared index file. This mode is designed for very large
indexes that take a significant amount of time to read or write.
+--untracked-cache::
+--no-untracked-cache::
+ Enable or disable untracked cache extension. This could speed
+ up for commands that involve determining untracked files such
+ as `git status`. The underlying operating system and file
+ system must change `st_mtime` field of a directory if files
+ are added or deleted in that directory.
+
+--force-untracked-cache::
+ For safety, `--untracked-cache` performs tests on the working
+ directory to make sure untracked cache can be used. These
+ tests can take a few seconds. `--force-untracked-cache` can be
+ used to skip the tests.
