What's a personality supposed to be for a StartupItem or Kernel

For kexts, it is documented here: (I just went to <http://developer.apple.com

Basically, it is a dictionary in your kext's plist that is used to
drive IOKit's passive matching. Also, when the driver goes through
active matching, the contents of the personality is passed to the
driver as its initial property list.
Note that any given kext can have several personalities, each offering
different matching criteria, and possibly other data left as hints to
the driver object that gets run later. This is why they are called
"personalities", since one kext can match on several different kinds
of devices and can alter its behavior based on the selected personality.
Also, your kext only has to contain personalities if it is going to
participate in IOKit matching. IOKit families typically don't have
personalities since they are loaded as libraries for other kexts, and
non-IOKit kexts obviously don't have personalities.
I'll let somebody else address StartupItems.
