How to make /etc/fstab "portable"?

[Benny Siegert <bsiegert%gmail.com@localhost>]

Hi!

This may be a stupid question but: Is there a way to make the entry
for the root filesystem in /etc/fstab just match whatever the kernel
used as the root FS?

I prepared a NetBSD image using Anita. When I transfer it to a
different hypervisor, the root FS is on sd0a, not wd0a, so the boot
stops when trying to run fsck. I would like it to run fsck, just using
whatever FS it is already using.
