Check the root mount, not hard-coded nvme partition

[fahhem]

I'm using another machine type, and the filesystem that should be checked isn't /dev/nvme0n1p1 anymore.

On my desktop, cat /proc/self/mounts | grep " / " | cut -f 1 -d " " outputs /dev/nvme0n1p2 because p1 is my /boot/efi. On my target machine, it's /dev/sda1

@fahhem which machine type is it?

It's a qemu-based "machine"
