Ok, sut to the chase.

Running just "su" alone meremly changes your effective UID.
By default, it is to root, but could to to another user.
It does not alter HOME, SHELL, USER, LOGNAME, and PATH.
That last one is important. A real root shell expects to have /sbin & /usr/sbin
in the PATH
HOME is also very important.

The home is not changed, so that files you write being root (or another
user) are written in the user's home. It can thus happen that config
files of the user become inaccessible to the user.

Which is why you should use:

"su -" to gain root powers. This way root created files end up in root's home directory.
