[ubuntu] Understanding apt-pinning

Hello !

At installation time of ZFS (to boot my system from a zsfs pool),
I followed the recommendation and added apt-pinning for this
package.

Ok, but I made a very big mistake and installed from
deb http://ppa.launchpad.net/zfs-native/daily/ubuntu

instead of

deb http://ppa.launchpad.net/zfs-native/stable/ubuntu

The pinning priority is 1001.

I fixed this error by modifying the pinning files.
What will happen, if I now update/upgrade ??
Will these version be kept on my box ??

Thanks so far and
best regards,
