Description Stilez 2019-02-18 09:46:57 UTC 
Imagine a zfs dataset (pool/mydata) with nested datasets (pool/mydata/subdataNNN).

At present one can "snapshot -r pool/mydata" and it'l also snapshot all nested datasets, and I imagine most users with nested datasets would do this.

But to check if anything has changed between snapshots, one cannot do "zfs diff -r pool/mydata". The option is missing. One has to diff each sub-dataset individually, which isn't intuitive or helpful.

Could -r be added to zfs diff?

You should raise this at https://github.com/openzfs/zfs

Closing the issue because FreeBSD is the wrong place to implement new ZFS features.
