Issue description

 Description:  in my opinion the RH134 is very poorly written. it is very hard to understand. (note: i have gone through RH124 in very detail):

in log architecture section (https://rol.redhat.com/rol/app/courses/rh134-9.3/pages/ch03) it says 
/var/log/boot.log corresponds to "Non-syslog console messages about system startup."

and in ch03s03, says "To send a message to the rsyslog service to be recorded in the /var/log/boot.log log file .. logger -p local7.notice "Log entry created on host""

what part of the logger command relates to boot.log, how am i to understand. 

another example is the explanation of the systemd-jounald and rsyslog service. it really does not show what the relationship with the syslog protocol, facilities (apps/programs), where the syslog messages originate. it really doesnt reveal the head or tail of the flow, just scrambled everything into a mashup.

most of the content so far till chap3 are very vaguely written. appreciate if its reviewed.
