Dom0 Precautions Dom0 Precautions
---------------- ----------------
As explained [here](/getting-started/#appvms-qubes-and-templatevms), dom0 should not be used for any user operations. There are several reasons for this: As explained [here](/getting-started/), dom0 should not be used for any user operations. There are several reasons for this:
1. Secure isolation among domUs (i.e., AppVMs, StandaloneVMs, HVMs, etc.) is the *raison d'être* of Qubes. This is the primary reason that we recommend the delegation of all user activities to some number of AppVMs. In the event that any given VM is compromised, only that particular VM is compromised. (TemplateVMs are the exception to this. If a TemplateVM were compromised, then every AppVM based on it might also be compromised. Even in this case, however, the entire system would not necessarily have been compromised, since StandaloneVM(s), HVM(s), and/or multiple TemplateVMs might be in use.) By contrast, if dom0 were ever compromised, the entire system would thereby be compromised. 1. Secure isolation among domUs (i.e., AppVMs, StandaloneVMs, HVMs, etc.) is the *raison d'être* of Qubes.

2. Due to the absence of convenience mechanisms in dom0 such as the inter-VM clipboard and inter-VM file copying, it is significantly less convenient to attempt to use dom0 for user operations (e.g., password management) in conjunction with AppVMs than it is to use another dedicated AppVM (e.g., a "vault" VM). 2.

In case of template-based qubes, the private storage (the /home directory and user files) can be changed in the qube's own settings, but the system root image is [inherited from the template](/getting-started/#appvms-qubes-and-templatevms), and so it must be changed in the template settings.
