the answer is yes actually. if you want a host you can change, use plain=
=20
fedora/rhel/centos as the host.
Fabian can reply to the rest.
Yep. Node has a read-only root filesystem, which has some overlays to
allow limited changes.

Do you mean collissions here, or can you explain it a bit more.

Could you please explain abit more about your setup.
If you have a SAN, an all LUNs of it are visible by all hosts, and you
install Node on more than one host, then it could come to collsisions.
Node is using some predefined LV names, e.g. Root, which will cause
collisions if there are more LUNs with LVs which have the same name.
