No CJDNS needed I assume?

Maybe we should have a module that aliases the hostname command to do this in /etc/profile or something? Do we want to make this a module?

I don't think you want to do hostname. changed I profile.

to many services depend on it. hostnames shouldn't be changed randomly either.

in a config screnario it should suggest a reboot after being changed.

I don't know what you are saying here.

Why did you make this script in the first place? Just in case?

Came as part of my backup/restore script i was toying with. You would need to rename the node when you restore your cjdns keys.

I meant you dont want to change the host-name in the profile. This requires the user to login to trigger this. Hostnames are set/changed much earlier in the boot process.

But its not a problem if we dont need to keep changing them :)

Alright then a systemd unit maybe?

But maybe this issue should just be closed, and you can add this as a contrib script.

What are you thinking of doing with this file? There is some hostname stuff going on now in #394, and this should be a contrib file if #394 doesn't do enough. Can this issue be closed?
