I recently discovered /etc/environment, which seems a more standard way to setup simple environment variables than scripts, but I was wondering if there was a way to back-reference environment variables in the /etc/environment file.

That is, I have this:


If I try to add $JAVA_HOME/bin to the PATH definition, however, I get $JAVA_HOME/bin, and not the interpolated variable. To remedy this, I'm creating in profile.d to add the /bin entries to the path, but this seems sloppy and disorganized.

Is there a way to backreference the environment variables in /etc/environment?
