svn commit: r344569 - in head/cddl/contrib/opensolaris: cmd/zfs lib/libzfs/common

> Nested zfs filesystems seem not to be handled properly or possibly not supported any more. This explains my mail gateway also not mounting all filesystems in /home. It was odd that dovecot stopped working.

> Generally this has screwed up sites that have hundreds (in my case 122) zfs datasets. The work around might be to script testing each mount, unmounting and remounting if necessary.

Thanks for the feedback, I’ll try to reproduce this on my side.
