OK ... what would be the benefit of booting and updating the livecd as
compared to just installing and updating CentOS on the flash.
There is nothing special about the RPMS on the LiveCD as compared to
The only possible thing I see as an advantage would be the fact that the
OS was NOT WRITABLE .. however, by rolling in the overlay feature, you
would be over riding that.
