Using tar to extract the contents of a .iso should work. You might end
up with oddities to do with file ownership and permissions, but you
should be able to fix that by suitable application of mtree(1).
Alternatively you can grab the actual installation images from the
install media -- that's any of the .txz files under /usr/freebsd-dist
for 9.0. These are actually rather easier to use than the equivalents
under 8.x or earlier: you get about 5 .txz files, not all of which are
necessary to boot the new system. For a minimal install on a 64bit
platform you'ld need base.txz, lib32.txz and kernel.txz. Just untar
those in the root directory of the system you're building (preserving
permissions and ownership) and you should be good to go. [Assuming
you've already done all the partitioning and creating filesystems and
installing boot-blocks stuff required, of course.]
Cheers,
Matthew
