ZFS Do not take snapshots of cache directories

[Alain De Vos]

I have,
zfs mount

ZT/nosnapshot/ccache            /ZT/ccache
ZT/nosnapshot/xcache            /ZT/usr/home/x/.cache
ZT/ROOT/default                 /ZT/ROOT/default

Is this a good way of working ?

I thought ZFS snapshots worked at the dataset level, not the mountpoint level?
But in general I would think snapshots of cache directories are worthless.

Another method is to set user properties on the datasets to mark them for snapshot or not.

zfs set user:snapshot=no ZT/ccache
