The root folder is shared, only the /home is unique for each VM. Does that mean that is I instal anything with sudo in one VM, it will affect the template and therefore all other VMs?
When you install software in /usr or /opt in the template VM it will be visible in all the user VM's that use that template. The settings to automatically launch daemon processes may need to be enabled for each AppVM depending on both yours and the particular software package requirements. You may not necessarily need a cron job or a daemon to run in every AppVM instance, for example.
If you instead install software in the AppVM's /home/user/* or /usr/local/* (basically any directory automatically remapped from the private volume /rw/* ), then the software will be available only within that single AppVM.
Where it makes sense to install a particular third-party software package depends highly on what that specific software needs in order to function properly. If the software is installed locally in /usr/local but then still wants its configuration files to be in /etc, or needs cron, then you may need to work around that specific problem with either copying the configuration file separately into the template VM /etc, or else using some magic scripting during the AppVM startup to copy the config file into the right location before the software that needs it is actually started. There is usually a workaround that will get the job done, but you may need to learn a bit more about how each software package works than you normally would on some other less secure system.
