Hi, I just tried replicating a zfs dataset, which failed because the dataset has a mountpoint set and zfs received tried to mount the target dataset to the same directory. I.e. I did the following: $ zfs send -R mypool/hg at 20090615 | zfs receive -d backup cannot mount ''/var/hg'': directory is not empty Is this a known issue or is this a user error because of -d on the receiving side? This happened on: % uname -a SunOS azalin 5.10 Generic_139555-08 sun4u sparc SUNW,Sun-Blade-2500 - Thomas
