Maybe it is a bit tricky for a general solution, since variables are defined and named differently on the different OSes?... As a workaround you could probably put a string replacement procedure into your QGIS.bat? We used e.g. a "#USERPROFILE#" string, as a placeholder, which got replaced when a custom QGIS2 folder template - containing the QGIS.ini - was copied to a new user... Not too trivial to replace a string in a text-file on Windows using batch (I understood from my colleagues)...

"Fully portable" means that I simply can install QGIS by copying the QGIS program directory to a location on the users PC and start QGIS by double clicking on the QGIS.bat file in the "..\bin" directory. I've reached 95% of my target by using the OSGeo4W installation as a template and making some modification the the start-up bat file. Mostly by using the --configpath qualifier to 1) redefine the location of the QGIS user directory .qgis2 and 2) not using the registry to save option values. By using the --configpath qualifier QGIS creates and uses the .qgis2\QGIS\QGIS2.ini file to store option values normally located in the registry. Some of these values are path definitions: example: Configuration\SAGA_FOLDER=C:/OSGeo4W/apps\\saga Configuration\GRASS_WIN_SHELL=C:/OSGeo4W/apps\\msys Configuration\R_SCRIPTS_FOLDER=C:\\OSGeo4W\\.qgis2\\processing\\rscripts I would like to use environment variables as part of the path definition in the ini file like this: Configuration\SAGA_FOLDER=%OSGEO4W_HOME%/apps\\saga Configuration\GRASS_WIN_SHELL=%OSGEO4W_HOME%/apps\\msys Configuration\R_SCRIPTS_FOLDER=%QGIS_USERDIR%\\processing\\rscripts (OSGEO4W_HOME and QGIS_USERDIR is environment variables, that contains the path for the QGIS program directory and the QGIS user directory) The problem is, that QGIS doesn't interpret the %......% as a environment variable and replace it with the value of the variable but simply interprets it literally resulting in paths containing "%" - signs and environment variable names. Is there a method to get QGIS to interpret the environment variable and replace it with the content of the variable ? Or should a put it on the wish list in the bug tracker ?
