su - starts a login shell for root. Info page says:
su - Make the shell a login shell. This means the following. Unset all
environment variables except `TERM', `HOME', and `SHELL' (which
are set as described above), and `USER' and `LOGNAME' (which are
set, even for the super-user, as described above), and set `PATH'
to a compiled-in default value. Change to USER's home directory.
Prepend `-' to the shell's name, intended to make it read its
login startup file(s)
So, this does two things I don't want:
Change to ~/root
Uses root .bash_history. I want to use the john's history
