I noticed you blurred out the IP address with the -I option before the merch ad, but left it visible after the ad.

At 8:22 you forgot to shadow your IP addresses (IPv4 & IPv6). Thank you for the quality of videos. BR.

like for hostnamectl - haven't known of it. Nice.

This is why i am moving to Void Linux. Systemd is not complete and still need people to know how to adjust Hostname properly.

I see you put the FQDN in /etc/hostname on your main server, not just the hostname but my hostname (1) says the following:

"The recommended method of setting the FQDN is to make the hostname be an alias for the fully qualified name using /etc/hosts, DNS, or NIS."

and

"Historically [/etc/hostname] was supposed to only contain the hostname and not the full canonical FQDN. Nowadays most software is able to cope with a full FQDN here."

Are there any downsides to either approach which we should be aware of?

Thanks for all your excellent videos!

Can you do a video on manually partitioning a disk with LVM during the Debian install? I included the only video I was able to find on YouTube. It is 10 years old and goes way way too fast. I was able to get it done but it was a struggle to follow even at 0.25 speed

Installing on a laptop with a small drive but still wanted to keep /, /home, /usr, and /var on separate partitions while having the ability to resize if it became necessary. The automatic partition settings in Debian didn't work for me. I know everyone says to just do one partition on small drives but I have found that gets you into more trouble when something fills up and you have no place to go.
