Here's what I do
After building world && kernel:
# cd /usr/src/

# make installworld DESTDIR=/to/path/with-2Gig-space

# make distribution DESTDIR=/to/path/with-2Gig-space

(you need a slice with ~2G space available)

Then:

# mkisofs -b boot/cdboot -no-emul-boot -r -J -V "FreeBSD_<VERSION>_Install" -publisher "<SOME_NAME>" -o /path/to/put/NEW_INSTALL.iso /to/path/with-2Gig-space


Hope it makes sense to you. :)
