It didn't create any .astropy/ config files in the new location, and when I moved my $HOME/.astropy out of the way, it still created a new $HOME/.astropy/config/ directory upon import even though $XDG_CONFIG_HOME was set to a different location.  I didn't try debugging beyond that.

Looking into astropy/config/paths.py, this should be $XDG_CONFIG_HOME/astropy ,
and that directory has to already exist to be used as the config subdirectory - the docstring
of get_config_dir() can be a little bit misleading in that respect.
If setting $XDG_CONFIG_HOME should still be causing troubles and modifying your
astropy installation is an option, you might also try to hack paths.py to have get_config_dir
additionally search a third location.
