 Quite possibly.  The VM where I noticed the issue is using MBR
 partitioning, and when I tried the same sysinst selections on a VM
 using GPT partitioning, I couldn't reproduce the issue, either.
 
 On the machine where the problem appeared, the dmesg output includes:
 
   wd0: 3072 MB, 6241 cyl, 16 head, 63 sec, 512 bytes/sect x 6291456 sectors
   ...
   root on wd0a dumps on wd0b
 
 and on the one where I couldn't reproduce it:
 
   wd0: 2048 MB, 4161 cyl, 16 head, 63 sec, 512 bytes/sect x 4194304 sectors
   dk0 at wd0: "9d3a7eb9-b2d1-4815-b958-4e03783330cf", 3800960 blocks at 64, type: ffs
   dk1 at wd0: "5fc58598-78c4-4aa8-8140-5b928df58c64", 393216 blocks at 3801024, type: swap
   ...
   root on dk0 dumps on dk
 
 Also, the former is hosted on Linux/qemu/kvm, and the latter on NetBSD/qemu/nvmm.
