I think this should probably be filed as a bug. Is there a bugtracker somewhere on this site (bugzilla, cvstrac, etc.)?
When you start the install, "fdisk" is listed as an option. This is supposed to run sysinstall. The path to sysinstall that this option tries to call is incorrect. It tries to run "/stand/sysinstall". In FreeBSD 6, sysinstall is in "/usr/sbin/sysinstall".
While "basic" users may not need this, I could see many experimenters not wanting to use the entire drive on a new machine. fdisk/sysinstall is the only way to handle this.
For example, right now I'm setting up 5 new workstations for a business. We are happy with PCBSD in general, but I like to slice the disk in half so that in the future if they want to put another OS on for dual-boot they can, without having to fiddle with partition magic or similar.
The typo is in the file "PCBSDStart.sh" on line 78. Just change the path to reflect the new location.
wish there was a bug-tracking db available for this project, I can't imagine how you guys can track things in a forum.
