* Firewalld lab mentions iptables in various places (including the schematic image), but apparently RHEL8 is using nftables now..

iptables is a symlink to xtables-nft-multi
ls -la /sbin/ | grep tables
lrwxrwxrwx. 1 root root 17 Feb 8 11:44 iptables -> xtables-nft-multi

firewall-cmd --list-services is returning cockpit in the list as well. The lab doesn't mention this in the results. It seems it is previously configured in the VM. remove it before final snapshot.

lab still does not link to next one

My nitpicks from latest trial:

• 10.1.4 - a bit confused, I have just done this "start/enable" combo - if it does not work, repetition won't help
• 10.5.3 - dd is to remove one line, dG all lines till the end of the file
  • when we are removing whole content, what was the point of copying the file in a first place?

Cleaned up sections 10.1.4 by adding additional explanations. As fir 10.5.3, we really don't need this section and I have removed it.
