This is how I create my images:
http://www.wifibsd.org/support/netbsd-on-cf.txt

I create a directory with all the files, create a file system with makefs and 
insert it into the kernel.
Then I create disk image with vnconfig create file system and bootstrap it and 
mount created partition.
Copy over the kernel and boot files and then this image file can be dd'd to a 
CF.

I guess I misunderstood something then, I'd need to just cp all the files to my 
vnd and do not use a memory disk.
What I wanted was one file with rootfs which would make it easier to upgrade 
the system, uploading one kernel file and replacing the old one.

Thanks,
Marcin.
