          Priority: medium
            Bug ID: 76102
          Assignee: systemd-bugs at lists.freedesktop.org
           Summary: hostnamectl set-hostname destroys /etc/machine-info
        QA Contact: systemd-bugs at lists.freedesktop.org
          Severity: minor
    Classification: Unclassified
                OS: Linux (All)
          Reporter: brian.harrington at coreos.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: general
           Product: systemd

While doing some work in trying ensure hostnames get set correctly on CoreOS I
found that running hostnamectl set-hostname would destroy the file
/etc/machine-info.

In this case the hostname "host-10-0-0-7" is the hostname assigned via DHCP. 
The file /etc/machine-info was created by hand and the system was subsequently
rebooted.
