How about including the URL of the ZFS tuning guide in the warning message: http://wiki.freebsd.org/ZFSTuningGuide It contains all the necessary information for both i386 and amd64 machines. It can also easily be updated if necessary so people always get the most up-to-date information. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
