I agree. We should try to reduce the number of ZFS install howtos and
instead put our efforts into bringing it into the handbook. Maybe some
of these howtos are better serves as articles showing alternative ways
of doing these. I know that filesystem layout can be a very personal
thing for many users who want to lay out things their way and none
other. But we could give new users guiding principles on how to do the
basic setup and then help them make the right decisions for their
environment based on the experience gathered from these wiki pages.

Yes, I had a quick glance at it and I especially liked the first part
using SSH from the beginning.

Yeah, tuning the system for ZFS usage (like reserving enough memory
for ARC and such) could also be part of such an article or handbook
chapter.
