Accoding to the FHS[1]:
  Utilities used for system administration (and other root-only
  commands) are stored in /sbin, /usr/sbin, and /usr/local/sbin. /sbin
  contains binaries essential for booting, restoring, recovering, and/or
  repairing the system in addition to the binaries in /bin. [18]
  Programs executed after /usr is known to be mounted (when there are no
  problems) are generally placed into /usr/sbin. Locally-installed
  system administration programs should be placed into
  /usr/local/sbin.
