Also, please suggest the more secure command (if that’s a thing,) for example using
echo "text" >> .Xresources
orcat << EOF | tee .Xresources
ornano
orvim
, or something I haven’t mentioned.
You could edit the config file in another qube and qvm-copy it to your default-mgmt-dvm.
Generally, I think it is not necessary to even have an xterm installed. You can use qvm-console-dispvm. See NOTE below.
When said the more secure command, then only say its security risks; you don’t have to say the security risks of others that we’ll not use anyway.
I have asked a few things about that special qube in the past, as I was/am willing to use a minimal template for it (NOTE: but have not explored further since then, due to lack of free time). In case you are interested:
