Make zfs-share service resilient to stale exports
The are a few cases where stale entries in /etc/exports.d/zfs.exports will cause the nfs-server service to fail when starting up. Since the nfs-server startup consumes /etc/exports.d/zfs.exports, the zfs-share service (which rebuilds the list of zfs exports) should run before the nfs-server service. To make the zfs-share service resilient to stale exports, this change truncates the zfs config file as part of the zfs share -a operation. Reviewed-by: Allan Jude <allan@klarasystems.com> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Don Brady <don.brady@delphix.com> Closes #13775
