I've noticed recently (not sure when this started, maybe on the 12->13 transition, which would be the same as the old ZFS to OpenZFS transition for us) that inheritance for the `readonly` property is broken.
Here is an example: [root@nfs-prod-11 /home/wollman]# zfs set readonly=on export/cl [root@nfs-prod-11 /home/wollman]# zfs get readonly export/cl/u NAME PROPERTY VALUE SOURCE export/cl/u readonly off temporary The child filesystem `export/cl/u` should have inherited the readonly setting from `export/cl` but instead it (and all other children) have overridden it, and I have to manually `zfs inherit readonly` on all of the children to get the proper behavior. This is quite surprising, and the first time it happened I was sure that something had gone wrong. -GAWollman
