3.9 CentOS Configuration - misleading info

Hi,

just want to report that in 3.9 CentOS configuration section of the course it is said:

The hostname is configured by changing the HOSTNAME=xxx line in the /etc/sysconfig/network file.

However, it is not specified which verion of CentOS is that actual for.

My point is that LFS211 course seems to be focused (and actively pointing) on newer systemd distros and not specifying CentOS version in this section may confuse a student, because for systemd based CentOS 7 the hostname configuration file would be /etc/hostname rather than mentioned /etc/sysconfig/network file in CentOS 6.

Currently LFCS and LFCE exams are offered only in systemd-based CentOS 7, so obviously 3.9 sectoin should be edited. Thanks.
