BSDInstall ISO images

[Nathan Whitehorn]

I've spent some time integrating bsdinstall into startup of install CDs, 
mostly related to building useful live-CD-based installers. An i386 
image can be found here (other architectures may follow, as my very slow 
DSL line permits):

http://people.freebsd.org/~nwhitehorn/bsdinstall-i386-20110108.iso.bz2

The source for this can be found at:

svn://svn.freebsd.org/base/user/nwhitehorn/bsdinstall

The bits related to live CD usage are the testsystem.sh and rc.local 
files. Instead of running sysinstall as an init replacement, I have 
written a small rc.local script that gives the user the option to either 
start the installer, open a single-user-mode style shell, or to continue 
to boot to a multi-user live CD. Also, instead of the md root used by 
sysinstall, this just boots from the CD directly. This prevents the need 
for sysinstall's media selection, since the distribution files are in 
the mounted root file system.

I would appreciate any comments or test results.
