You're probably thinking of my ports/sysutils/makefs (borrowed shamelessly
from NetBSD).  Given a directory tree and some options (size of disk image,
number of inodes, UFS1 vs. UFS2, etc.) it will create a UFS image.

I use it in my depenguinator to install FreeBSD onto remote linux systems.
(Extract the release tarballs into a staging directory, add some magic,
build a UFS2 image, dd the image to the hard drive, and reboot.)
