If you get error messages like
cannot remove directory for ~/.something/Cache: Directory not empty at /usr/bin/unburden-home-dir line 203
there is likely a process running which still has files open in that directory or a subdirectory thereof.
Exit that program and try again. unburden-home-dir is idempotent,
i.e. it can be called several times without doing different things.
In case unburden-home-dir moved something it wasn’t expected to, you
can try to undo all of unburden-home-dir’s doing by running
unburden-home-dir -u
Nevertheless this functionality is less well tested as unburden-home-dir’s normal operation mode, so it may not be able to undo everything.
unburden-home-dir’s undo mode (of course) can’t undo modifications
where it has been told to remove all files and create an empty
directory instead. See the r action in the Configuration Files
section below.
