Well no, I posted the question because that doesn't do it.
zfs list -r rpool
[...]
rpool/dump 1.50G 292G 1.50G -
rpool/export 15.9G 292G 21K /export
rpool/export/home 15.9G 292G 22K /export/home
rpool/export/home/reader 15.9G 292G 11.5G /export/home/reader
[...]
# zfs snapshot -r rp...@somedate
# zfs snapthot rpool/someotherdate
cd /rpool/.zfs/snapshot
diff -r somedate someotherdate
No difference, and there is no
rpool/dump
rpool/export
rpool/export/home
rpool/export/home/reader
under either snapshot... not to mention all the other stuff shown with
zfs list -r rpool
that I snipped.
