When installing DragonFlyBSD 4.8 in VirtualBox 5.1.16 (host is running Ubuntu MATE 16.04, Linux 4.4.0-66-generic) on a virtual 30 GB IDE harddisk, boot0cfg crashes:

,-<<< Executing `/sbin/disklabel64 -B ad0s1'
`->>> Exit status 0:

swap_pager: out of swap space
,-<<< Executing `/usr/sbin/boot0cfg -B -o packet ad0'

However, when the VM is being booted from the virtual hard disk, the system is usable.
