Clone a melange VM

You can select any VM and clone it in VM.

For simpler VMs:

• provide a hostname and ID for the new VM during clone, and hit OK
• wait for proxmox to clone it (how do you monitor this, not sure yet...)
• start it and open a console
• the hostname will be old, fix it

sudo hostname mahhost
sudo emacs -nw /etc/hostname

• get the MAC address

ip a

• add an entry to dnsmasq and restart the service

🌵 m@bitpost  [~/config/etc/dnsmasq.d] emacs -nw /etc/dnsmasq.d/mdm_lan_dnsmasq.conf 

• reboot the VM
• verify IP and ssh
• ~/config will be pointing to the config of the old box, migrate it
  • create a new development/config/ubuntu/mahhost as a copy of the cloned one
  • point ~/config to that

[~] cd development/config/ubuntu && cp -rp clonedhost mahhost
[~] cd && rm config && ln -s /home/m/development/config/ubuntu/mahhost config
[~] cd config && grep -i clonedhost * -R # update em all

• Wow, for some reason, /etc/fstab matches original cloned VM, and is still working? OK!
• Check config hostname, it is likely that the old clonedhost hostname ws changed instead of the new mahhost
• run setup_stow.sh

There will be some things to fix, as explained by setup_stow.sh warnings. For example, removing existing ~/.bashrc symlink so it can be recreated. A bit scary, but go for it it's a fucking clone! MWAHAHAHA!

rm ~/.bashrc
sudo rm /etc/fstab /etc/hostname 
$ m@ig1  [~] sudo mv /etc/systemd/journald.conf ~/backup
$ m@ig1  [~] sudo mv /etc/systemd/networkd.conf ~/backup
setup_stow.sh

• update bitpost hosts file, redistribute it (exhausting...)... does setup_stow.sh on each machine do this for us? i can't remember...
• Add the new config folder, and commit all the config changes
• reboot and verify it all
