No diskspace in varlibqubes for installing templates

I looked briefly at the option of resizing [the dom0 root filesystem] to have more space but it looked cumbersome and decently data loss dangerous.

Shouldn’t it just be something like

sudo lvresize --size 40G /dev/qubes_dom0/root
sudo resize2fs /dev/mapper/qubes_dom0-root
