[Note: This is a feature request, not a bug report.]
The feature/improvement consists of extending the exports(5) format to allow multiple host/permission tuples on a single line.
It would be desirable to accommodate the format used by Linux, see, e.g., https://linux.die.net/man/5/exports .
This would bring the following advantages:
- ZFS sharenfs settings could be shared with Linux systems.
- Multiple ZFS sharenfs options could be set in one line, thereby finally solving the long-standing bug #147881.
- In general, the exports(5) would be easier to read (arguable).
