I'll have to see about upgrading this system (there's a separate pool for the OS), I guess. Which FreeBSD version(s) include that feature? Would 10.3 be okay, or would I have to go all the way to 11.0? Hrm, maybe I'll play with an updated mfsBSD USB stick instead, and see if things work better with that, first. Thanks for the info!! --=20 Freddie Cash fjwcash@gmail.com
