Bug Description

"/bin/mount -t zfs -o defaults,atime,dev,exec,rw,suid,nomand,zfsutil rpool/zones/bla /zones/bla"
fails, if env var POSIXLY_CORRECT is set, because it calls
"/sbin/mount.zfs rpool/zones/bla /zones/bla -o rw,zfsutil", which is obviously a bug. Options should always come first and operands last ...

AFAICS the problem is libmount/src/context_mount.c:exec_helper() which is uses operands in a wrong/not posixly incorrect way. See also http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap12.html
