At end of install to hard drive pfSense directs user to eject CD but doesn't unlock CD ROM drive.
While testing pfSense 2 RC3 on ESXi 5.0.0 I received an error that the install CD was still locked by the operating system when I tried to eject it after being prompted to do so.
use force-eject in ESXi
Reason to fix this issue at all:
some users might not immediately know they can safely ignore the errors which scroll endlessly after force-eject
