Hello,

If you're trying to put BSD on a USB/Compact Flash card you should look 
at the miniBSD scripts.

https://neon1.net/misc/minibsd.html
http://www.onlamp.com/pub/a/bsd/2004/03/11/Big_Scary_Daemons.html
http://www.freebsd.org/doc/en_US.ISO8859-1/articles/solid-state/ro-fs.html

The provided scripts should apply with little modification against 
DragonFly. I've used the above scripts as a starting point to install 
FreeBSD 4 (inc Perl 5.8, Apache and Exim) on a 64Mb compact flash card 
mounted read-only. (~48Mb in use.)

Regards

Gary
