[Bug 1052664] Re: 12.10 cloud-init injects comment into /etc/hostname

[Scott Moser]

and, in fact, that *is* ok:
$ cat /etc/hostname; echo ; echo ==
# Created by cloud-init
domU-12-31-39-02-10-6D
==

$ sudo hostname --file /etc/hostname; echo $?; echo "hostname=$(hostname)"; echo ===
0
hostname=domU-12-31-39-02-10-6D
===
$ sudo hostname -b -F /etc/hostname; echo $?; echo "hostname=$(hostname)"; echo ===
0
hostname=domU-12-31-39-02-10-6D
===
$ sudo hostname -F /etc/hostname; echo $?; echo "hostname=$(hostname)"; echo ===
0
hostname=domU-12-31-39-02-10-6D
===


So something else must be reading that and setting the hostname.

cloud-init log shows:

so it sure looks like *it* is calling hostname corectly.
