That's potentically problematic.
If the user puts ". ~/.bashrc" into their ~/.grass.bashrc file, and
their ~/.bashrc sources ~/.alias, then having init.sh source ~/.alias
would result in it getting read twice.
Having Init.sh set up a .bashrc file is one thing (that name is built
into bash), but the ~/.alias file is something that specific
distribution vendors have cooked up for use by their default ~/.bashrc
(etc) scripts. If you aren't using such a platform, ~/.alias might not
even contain bash code.
