the clfs user. The final system
should be owned by root.

Important
The commands in the remainder of this book must be performed while
logged in as root. Check that
${CLFS} is still set:
echo ${CLFS}
Make root the owner of the entire
CLFS system.
chown -Rv 0:0 ${CLFS}
The following files are to be owned by the group utmp not by root.
chgrp -v 13 ${CLFS}/var/run/utmp ${CLFS}/var/log/lastlog
During the installation of Util-Linux-ng configure was instructed not change the ownership of certain programs. Correct that ownership now that we have sufficent privileges.
chgrp -v 4 ${CLFS}/usr/bin/write
chmod g+s ${CLFS}/usr/bin/write
The following device nodes need to be created for the system to boot.
mknod -m 0666 ${CLFS}/dev/null c 1 3
mknod -m 0600 ${CLFS}/dev/console c 5 1
