Topic: rc-service dmcypt and lvm
Here on the forum and in the guides you can read that you need to install and run service dmcypt and lvm.
If dmcrypt I understand what it is, and what it is needed for (if you don't know what it is for it means that you don't need it)
I have no idea what LVM is for, I have several encrypted installations with LVM, I don't have RC-Service LVM anywhere, and Hyperbola works.
What is LVM and why should I run it?
