Devuan 64 Alpha2 install (netboot image). "No root filesystem"
I've booted the Alpha2 iso but it doesn't seem to be able to find any partitions. From the partition menu ("LVM" "Guided" or "Manual") I select "Manual" but then get a dialog stating "No root file system defined". The installer seems to be jumping ahead from partitioning to installing without allowing me to setup partitions or filesystems.
I have a 4G raw partition as /dev/sdb1 (formatted with ext4 and set 'active') which I intend to use for "/" and then use LVM for /usr, /var, /home and /tmp. I don't want to re-partition the entire disk as it would hose my current Ubuntu desktop install on the existing LVM partitions.
