Good advice - thanks!

I've added a paragraph to the LIVE UPGRADE section of the documentation:

   pca always installs the patch for the patch installation utilities
   first to avoid possible bugs in patchadd. When patching an inactive
   BE, this patch should be installed manually to the active BE, as its
   patch installation utilities are used even when root=DIR is set.

I hope that's clear enough ..
