See the man pages for su and sudo (a package).  In particular see -l and
-m to su, and -E to sudo.  What I do is set environment variables I want
in my own dotfiles, and then use "sudo -E" to get a root shell with my
variables.  There are lots of ways to do it, and it's really just a
matter of preference.
