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 abigger 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 themall?
For starter I use recursive grep on '/etc' '/home' ... -- John Doe
