  71. .Ss Example 1 : No Creating a ZFS Clone
  72. The following command creates a writable file system whose initial contents are
  73. the same as
  74. .Ar pool/home/bob@yesterday .
  75. .Dl # Nm zfs Cm clone Ar pool/home/bob@yesterday pool/clone
  76. .
  77. .Ss Example 2 : No Promoting a ZFS Clone
  78. The following commands illustrate how to test out changes to a file system, and
  79. then replace the original file system with the changed one, using clones, clone
  80. promotion, and renaming:
  81. .Bd -literal -compact -offset Ds
  82. .No # Nm zfs Cm create Ar pool/project/production
  83.   populate /pool/project/production with data
  84. .No # Nm zfs Cm snapshot Ar pool/project/production Ns @ Ns Ar today
  85. .No # Nm zfs Cm clone Ar pool/project/production@today pool/project/beta
  86.   make changes to /pool/project/beta and test them
  87. .No # Nm zfs Cm promote Ar pool/project/beta
  88. .No # Nm zfs Cm rename Ar pool/project/production pool/project/legacy
  89. .No # Nm zfs Cm rename Ar pool/project/beta pool/project/production
  90.   once the legacy version is no longer needed, it can be destroyed
