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. http://svn.pcbsd.org/pcbsd/current/pc-sysinstall Submitted by: kris@ Sponsored by: iX Systems
