Christopher --- would it suit your release process to have a standardized,
prepopulated ~/.emacs.d/eshell/alias file for your users?

I have checked that one does not need to actually define an alias through
eshell.  It suffices to modify the alias file.  (Although, to figure out
what to put into the master alias file, you may have to do experiments with
eshell.)
