Commit r240315 into 9.1-release

[Mark Saad]

All
 Can someone merge in r240315 into the 9.1 release. This fixes a few bugs in pc-sysinstall . I am planning on using pc-sysinstall for automated network installs of 9.1-RELEAE ( not pc-bsd ) much akin to jumpstart with sysinstall in past releases .  With out this commit a few options for disk layouts that were supported in all prior versions of sysinstall do not work in pc-sysinstall .
