Distribution: Debian Wheezy/Jessie/Sid, Linux Mint DE
I don't know what exactly is the problem. But changing the host name is routine in Debian. In /etc grep for the old host name. This should turn up 4 files. Probably less in your case because you already commenced the change. Anyway, edit all the files that you find replacing the host name.
I did this in Squeeze most recently. Will do this week in Wheezy. Maybe there is something moved to a subdir in the conf.d style which becomes more current.
grep 'newname' /etc/* returns one file: /etc/hostname
grep 'oldname' /etc/* does NOT return any file, still the prompt says root@oldname, also -R option did not find any relevant files
PS: just realized that I had found earlier the oldname in the /etc/hosts file, last line, own IP. Changing this entry did not have any effect. It explains though that the hosts file did not come up with grep.
jlinkels: thanks for the link, the only new point was a possible interference of DHCP which (as far as I can tell) is not active on this host. Also out of ideas for now. Will leave this open and document the solution as soon as any comes up.
