Can I ask why do you need this sort of patch?

You can accomplish everything the patch achieves AFAICS by just setting 
the $XDG_CACHE_HOME, $XDG_CONFIG_HOME and $XDG_DATA_HOME environment 
variables before running any one of the Tracker binaries. In fact, this 
is what I do in the script I wrote to have localised Tracker DBs for 
different datasets.

I would like to avoid adding more config and maintenance burden to 
specify locations. We already have a lot of that.

Is there some reason the env vars are not enough?
