 If your are lucky enough to have IPV6 and a /64 IPV6 scope, it won't be a problem to assign a public IPV6 to each YunoHost.

 Don't forget to regularly upgrade your YunoHosts VMs/LXCs to the last release doing: revert back to last happy/healthy YunoHost snapshot and doing `yunohost domain cert-renew --no-check && yunohost tools update && yunohost tools upgrade --apps && yunohost tools upgrade --system && apt autoremove`. Take a snapshot after that successfull full upgrade. And after some testings or one week later, remove old snapshot. PS: that can be automated...

 Doing that you will have all the time a full/ready to go YunoHosts infrastructure for advanced packagers. And if require, you can have some VMs/LXCs runnning the YunoHost testing or YunoHost next Debian main version.
 
 ## Having your packages/commits available in each VMs/LXCs
 There are several ways to have your freshly created package available from each VMs/LXCs
 1- Do an ssh from the YunoHost VM/LXC to a central repository on your computer
-2- rsync you central repository to each VM/LXC
