I noted that the book contained

groupadd -fg 27 polkituser &&
useradd -c "Policy Kit Daemon User" -d /dev/null -u 27 \
    -g polkituser -s /bin/false polkituser || [ $? == 9 ]

is the [? == 9] just to change the command to true if the useradd
command fails?  I have not seen BLFS do this anywhere else.
