Describe the problem you're observing

Mounting ZFS filesystems fails with
failed to lock /etc/exports.d/zfs.exports.lock: No such file or directory

Further mount attempts may fail with
cannot mount '<dataset>': filesystem already mounted

And zpool export -f <pool>
results in
cannot unmount '<dataset>': no such pool or dataset

Describe how to reproduce the problem

zfs mount -a

Include any warning/errors/backtraces from the system logs

Can be provided upon request indicating what particular log is needed.

Noticed the same error message when performing a zfs mount -a following upgrading from ubuntu 23.04 to 23.10:

failed to lock /etc/exports.d/zfs.exports.lock: No such file or directory

Curiously, the command exits cleanly (exit code 0) and the expected mount actions actually occur.

Happy to provide further context from my end too!

I'm experiencing the same issue on my Void Linux machine. Linux 6.5.8, ZFS 2.2.0. Everything boots fine and works as expected. The error is printed twice on tty1 every boot though since ZFS 2.2.0.
