Bug description:
As per https://github.com/openzfs/zfs/issues/15930
ZFS and kernel 6.8 seem to throw EOPNOTSUPP on calling
copy_file_range, breaking a multitude of applications.
Upcoming noble (24.04) appears to currently include kernel 6.8 and ZFS
2.2.2.
One notable issue is when running Root on ZFS: systemd-sysusers will
always fail to create users/groups with the error "Failed to backup
/etc/{group,passwd}: Operation not supported" due to the call to
copy_file_range.
