You have confused me. I started to use Debian about 4 months ago because I no
longer want to build and update my custom built GNU/Linux systems, which I had
been doing for 20 years. Upon moving to Debian I looked up how to set the
host name and was instructed to set the host name as “host” with out any
“domain” part and then set a FQDN in /etc/hosts. Upon further research I found
out that is the proper what to set the host name since UNIX began.
I had been setting the host name to FQDN and the docs I read stated that was
incorrect.
Can you point to the docs that have information about the “long host names” as
I have not been able to find anything on that?
Sorry about sending the reply directly to you but this iPad won’t let fix that!
