Yes. Note, though, the part in the original package with the .path file which my original description said to copy to your /home/user/.profile file. You will want to edit and update that file (it's currently in usr/local/teTeX/) to make the setup consistent. And if you do, generate a new MD5sum and update DEBIAN/md5sums (actually, you will want to re-generate that file altogether because all the paths will be changed). And finally, edit DEBIAN/postinstall And be aware of potential issues with a re-installed version of your repackaged file, e.g. your existing edit of your .profile.
