I am really enjoying these projects. Thank you!
I finished an exercise successfully, but there were some questions I still have.
01: I was looking for the /etc/fstab files for my exercise to make a configuration persistent. I didn’t see the file on any of the app servers, so I wondered what OS I was using.
uname -a showed ubuntu.
cat /etc/os-release showed centos7.
Turns out, the exercise didn’t require an /etc/fstab entry, but I thought this was interesting.
02: The other thing I noticed is that /etc/hosts for nautilus systems seem to have two line entries in /etc/hosts for the primary ip address. This has caused me issues in the past, and now I typically just comment out the line for the non-fqdn line. (Which takes a little time) In my work experience, I typically configure my systems using the ip/fqdn/shortname. Just wondered if I am missing something with the two line entries. I see it on all projects I think.

172.16.238.10 stapp01.stratos.xfusioncorp.com stapp01 ( Config I normally would expect)
172.16.239.3 stapp01.stratos.xfusioncorp.com stapp01 (Not talking about this line)
