It seems that the distro (FreeNAS) automounts FreeBSD procfs on /proc of FreeBSD jails so the mount of linprocfs never actually happens. I will have to further testing to confirm this, but from outside the jail I can see that procfs is mounted on jail's proc. Since FreeNAS runs on FreeBSD that looks to me like FreeBSD's procfs is mounted on jail's /proc and is likely why the mount of linprocfs from inside the jail (by freebsd-utils) fails (assuming of course the it's not actually a case of needing to hack on things so that linprocfs gets mounted prior to jail startup).
