zfs receive: -u can be ignored sometimes
It seems that zfs
receive -F -u would mount a received filesystem after receiving a full stream if a destination filesystem already existed (and, thus, got destroyed and re-created) and was mounted.
How to reproduce:
$ zfs create rpool/sandbox $ zfs create rpool/sandbox/from $ zfs create rpool/sandbox/to $ zfs snap rpool/sandbox/from@snap $ zfs send rpool/sandbox/from@snap | zfs recv -v -F -u rpool/sandbox/to receiving full stream of rpool/sandbox/from@snap into rpool/sandbox/to@snap received 41.7KB stream in 1 seconds (41.7KB/sec) $ zfs get mounted rpool/sandbox/to NAME PROPERTY VALUE SOURCE rpool/tmp/sandbox/to mounted yes -
This behavior can be problematic if the mountpoint property changes either because it had a non-inherited value or the stream contains properties because it has been generated with either -R or -p.
