I noticed the HASSIO 0.73.1 System option now comes with “Change Hostname” function.
I tried changing mine, went through the steps but failed to get the change.
I checked the System Log and got this:
18-07-15 23:34:57 INFO (MainThread) [hassio.host.control] Set Hostname MYNEWHOSTNAME
18-07-15 23:34:57 INFO (MainThread) [hassio.utils.gdbus] Call org.freedesktop.hostname1.SetStaticHostname on /org/freedesktop/hostname1
18-07-15 23:34:58 ERROR (MainThread) [hassio.utils.gdbus] DBus return error: b'Error: GDBus.Error:System.Error.EROFS: Failed to set static hostname: Read-only file system\n'
The last line indicates it is a read only file, any idea what step did i miss to do? Is there an extra action needed prior to executing the change hostname step?
