Yes, you can rename mountpoints, and always have been able to. It just didn't happen much before the arrival of ZFS. When you reboot the machine, it would have tried to mount the filesystem in the original location. Under ZFS, this would have created a new mountpoint for you. With UFS, you would have failed to mount the filesystem at all.
While this could theoretically be solved for the "target is a mountpoint", I'm not sure if it can be done and still be standards compliant, and it certainly can't be solved for arbitrary cases (rename /foo/bar, when /foo/bar/baz is a mountpoint). - Eric On Wed, Jul 25, 2007 at 03:33:36PM -0700, Dan Mick wrote: > I had a pool, p, with a filesystem p/local, mounted at /local.
