On Linux, su(1)'s "-p" flag makes sure the following environment variables are preserved: $HOME, $SHELL, $USER, and $LOGNAME. The flag isn't portable, and since we don't set HOME=$SPOOLDIR anymore, there's no reason to preserve these variables anyway. Without "-p", we also don't need to set HOME=$INSTALLUSER_HOME, as su(1) now does that for us.
