I've been using mount_null for quite some time to mount filesystems beneath chroot jails, and have had no problems. However, the man page for mount_null has had a warning (since 1995, apparently) that "IT DOESN'T WORK", and I know OpenBSD has removed nullfs support as of version 3.7 (per http://archives.neohapsis.com/archives/openbsd/2005-09/0198.html). The bug listed in that thread doesn't appear to apply to FreeBSD, as I was able to successfully null mount /dev and list its contents. So my questions are: 1. is nullfs actively supported on FreeBSD? If so, are there plans to continue supporting it? 2. If not, is there another way of mounting filesystems to alternate directories on the system, as linux's "mount --bind" does? Or will mount --bind be added to the FreeBSD mount command? Thanks -Jim Keller
