Bring in Kris Moore's pc-sysinstall shell script from PC-BSD. This

shell script is the back end logic necessary for an installer.  It
contains both query routines to allow a front-end installer to present
reasonable choices to the user and also action routines which allow
the front end installer to put a FreeBSD distribution onto a disk.  It
supports installing onto the usual suspects, as well as advanced
features like Mirroring, ZFS, Encryprion and GPT labels.

While this is only the back-end of the installer, it can do unattended
scripted installations.  In PC-BSD's world view, all installations are
scripted and all the front-end does is write the script.  As such, it
is useful in its own right.

This has been extensively tested over the past several releases of
PC-BSD.  However, differences between that environment and FreeBSD
suggest there will be a period of shake-out while those differences
are discovered and corrected.

A text-based front-end is in the works.  For the GUI-based front-end,
you can use the PC-BSD distribution.

Kris' BSDcan paper on pc-sysinstall is linked off his talk on the
BSDcan site:
	http://www.bsdcan.org/2010/schedule/events/173.en.html

The man page is written by Josh Paetzel, and I wrote the Makefiles for
the FreeBSD integration.  Kris wrote the rest.

This represents version r7010 in the PC-BSD repo.
