Fine.

Firstly, putting aliases into /etc/profile won't work. You need them in
non-login shells and they are not exported. So they need to be in a
bashrc.
Secondly, putting it into the global profile or bashrc is just rude.
Aside from very basic things like j=jobs and h=history, this kind of
clutter is just annoying to other users. Even on your own personal system,
you may one day share it with a visitor.
Just put it in /root/.bashrc, possible sourcing a common file.
For example, you could make a /etc/bashrc.local and source it in
/root/.bashrc perhaps.
Personally, I invoke su via a wrapper; it runs su and gets it to invoke
a shell with my own environment. (A plain, non-login su nearly does this
anyway.) Just be sure to use "su -" to get a real vanilla root shell
when doing installs or starting daemons; it ensures they don't get an
environment cluttered with possibly misbehaving stuff.
