Author: mav Date: Sun Feb 18 01:42:17 2018 New Revision: 329505 URL: https://svnweb.freebsd.org/changeset/base/329505 Log: MFV r323911: 8502 illumos#7955 broke delegated datasets when libshare is not present illumos/illumos-gate@1c18e8fbd8db41a9fb39bd3ef7a18ee71ece20da https://github.com/illumos/illumos-gate/commit/1c18e8fbd8db41a9fb39bd3ef7a18ee71ece20da https://www.illumos.org/issues/8502 The code in lib/libzfs/common/libzfs_mount.c already basically handles the case when libshare is not installed. We just need to not fail in zfs_init_libshare_impl. I tested this in lx and things work as expected. I also tested there trying to set sharenfs and sharesmb on the delegated dataset. Neither is allowed from within a zone. The spew of msgs from a native zone is not ZFS specific. I see the same spew simply running the share command.
