Hello,
Working under Debian, when I switch to root using `su', Emacs doesn't
load the init script located in my user's home folder, as the manual
says:
``if you run Emacs from a shell started by `su', Emacs tries to find
your own `.emacs', not that of the user you are currently pretending
to be [...] It gets your user name from the environment variables
`LOGNAME' and `USER'.''
The variables LOGNAME and USER have both the value `root'. The command
`logname' returns instead my own user name.
Is this an Emacs bug?

Thanks for replying. I see now that most of the environment variables
are kept with the `-p' option.
