I did have some system instability during my trial, though; I've put it down to a bad IDE HDD (because it gave issues when not part of a gvinum plex as well), but I didn't give it a serious amount of testing. As for the handbook, you seem to be correct. You might file a "doc" PR --- they'd probably appreciate having the opportunity to fix this. However, I do find gvinum(8) on my box.... Kevin Kinsey
