Okay, so it looks like I misunderstood your comment: you were
advocating for sourcing /etc/profile in the user's shell profile.

bash will actually load that file regardless, and on all Linux
distributions the result is that features such as bash completion
will be available to the user right after login, even with our
custom shell profile in place.

FreeBSD, of course, behaves a little differently ;) You have to
source the bash_completion script manually if you want that
feature, as /etc/profile is tailored to the classic Bourne shell
so it won't do that for you, and there is no such thing as a
global bashrc that you can use.

All in all, it's pretty simple to add, but I think it's okay for
it to be a follow-up patch. Are there more features you had in
mind?
