Ubuntu 16.04 proves even an LTS release can live at Linux’s bleeding edge

Re:Ubuntu 16.04 proves even an LTS release can live at Linux... by falcolas on Tuesday May 10, 2016 @09:35AM (#11666999)

Question for those who have an install of 16.04 - if you type `hostname -f`, do you get the "command not found" error? I didn't have time to dig into it, but the man pages indicated that `-f` was still a valid option, but it appears that `hostname` was shifted to quasi-function.

I came upon this while trying to bring up my vagrant development box against 16.04, part of which was to set the hostname via `server.vm.hostname`.

You mean in a console? Works fine here.

Seems very odd, here it works

  clemme@ubuntu:~ $ hostname -f
  ubuntu

  clemme@ubuntu:~ $ cat /etc/lsb-release 
  DISTRIB_ID=Ubuntu
  DISTRIB_RELEASE=16.04
  DISTRIB_CODENAME=xenial
  DISTRIB_DESCRIPTION="Ubuntu 16.04 LTS"

Yeah, does seem odd. Looks like I'll need to ping Vagrant, since `ubuntu/xenial64` is their managed box.
