>Description:
I decided to try -current & installed a snapshot from scratch.
Turns out in -current we've switched to using dk(4) in the regular kernel (not the install kernel), this results in a system which fails to go multiuser due to fstab created during install referencing wd(4) device.
At the single user prompt it's not possible to force a mount of the relevant device as root_device.
Editing the fstab to reference dk1 / dk2 instead of wd0a and wd0b for root and swap allows the system to boot as normal
