It's not just domainname and /etc/hosts. It's every frigging where.

now my ISP SMTP server is moaning.

think I got them all except cups is unhappy, I don't know why.


There's actually a wiki on this:

https://wiki.debian.org/HowTo/ChangeHostname

For cups you might look at

/etc/printcap

the part after rm=
  rm=einstein
     ********

Of course that part is the part to the left of the first dot in your
fqdn.

Anyway, good luck (my hostname is incorrect, but as it has never caused
me any misery, I've left well enough alone up to this point).

Oh, there's more in /var. I'm going to ignore the binary files as
I don't think they are current and I don't know how to edit them
anyway.
In fact the installation is a bit old I could do with tidying it
all up anyway so I might as well start afresh.


I  always start from scratch when I need to change the
hostname/domain on a host.
That's probably the only reason I need to start afresh!

Unless you're running an advertised server, in which case one would
wonder why you felt the need to change things (perhaps part of a
bigger disruption), I can only say I find this rather extreme.

Thanks for the caution.
As part of improving my network; I went for meaningless hostname and using CNAME record to better describe the host.

Years ago, I would clone a system (or build in a different box) and then
move it into its new home with very few files to alter. About the only
confusion caused was to ARP, and that only happened when I was on
thinwire ethernet and lasted a few minutes.

I've struggled to find a multitude of files with the name of the
domain in them. Beyond hosts and mailname, where are you finding them
all?

For starter I use recursive grep on '/etc' '/home' ...
