So in a general sense: 1. Is there a hard limit? 2. Do the type(s) of the mount(s) matter? 3. Does mounting in jails matter vs. mounting directly on the host? 4. And the $64 question, if I had a setup with lots of jails, and each had a nullfs, devfs, and 2 or 3 NFS mounts, how many jails could I have without causing an implosion? :) Thanks, Doug -- It's always a long day; 86400 doesn't fit into a short.
