No it doesn't, that said since the new release CD is a live file system =
(vs the old MFS on a CD kludge) it is much much easier to script your =
own install.
Especially with gpart it is fairly easy to setup a working system.
I use this at work - image.txz.?? is created from a chroot where I =
pre-build rather than using packages since it is a lot faster.
The original also does things like put certain settings in sysctl.conf, =
loader.conf and rc.conf.
I found it was a lot simpler to set this up vs doing something similar =
with sysinstall because sysinstall's environment was so restrictive.
Currently the user selects shell and then runs the script, but I am =
looking at modifying the release rc.local to add a menu option to make =
it simpler.
