Scripted Installs

[Robert Simmons]

I'm working on a scripted install using installerconfig. The man page
for bsdinstall(8) is fairly clear on the usage of PARTITIONS in that its
arguments are the same as the parameters portion of the scriptedpart target
listed above. Is there documentation for the parameters needed
for ZFSBOOT_DATASETS? I don't see this documented anywhere on that man page.

What is the full syntax of the parameters of ZFSBOOT_DATASETS?
