This doesn't work because `pwd` is expanded at the time you assign
this value to PS1. Also, contrary to for instance ksh, sh will not
expand variables when evaluating PS1.

prompt1="$(whoami)@$(hostname -s)|"
case $(id -u) in
0) prompt2='# ' ;;
*) prompt2='$ ' ;;
esac
cd()
{
command cd "$@"
PS1="${prompt1}${PWD}${prompt2}"
}
cd "${PWD}" # initialize prompt
