New Revision: 266555
URL: http://svnweb.freebsd.org/changeset/base/266555

Log:
  Fix syntax error thrown at the point of creating the root pool, caused by
  an embedded newline appearing within the options string surrounded by
  double-quotes. Rework the logic that goes into setting dataset options on
  the root pool dataset while we're here -- added two new variables (which
  can be altered via scripting) ZFSBOOT_POOL_CREATE_OPTIONS and also
  ZFSBOOT_BOOT_POOL_CREATE_OPTIONS for setting pool/dataset attributes at
  the time of pool creation. The former is for setting options on the root
  pool (zroot) and the latter is for setting options on the optional separate
  boot pool (bootpool) implicitly enabled when using either GELI or MBR. The
  default value for the root pool variable (ZFSBOOT_POOL_CREATE_OPTIONS) is
  "-O compress=lz4 -O atime=off" and the default value for separate boot pool
  variable (ZFSBOOT_BOOT_POOL_CREATE_OPTIONS) is NULL (no additional options
  for the separate boot pool dataset).
