systemkeychain [-v] [-f] -C [ password ] systemkeychain [-v] -t systemkeychain [-v] [-c] [-k dest_keychain ] -s keychain
Creates and manages the system keychain, /Library/Keychains/System.keychain . ( systemkeychain also creates /var/db/SystemKey , which presumably contains a randomly generated keychain password in encrypted form.) This keychain is used by system processes that run as root , such as daemons and boot processes, and is created automatically by the SecurityServer startup item.
