Turning the multihost property on requires that a hostid be set to allow ZFS to determine when a foreign system is attemping to import a pool. The error message instructing the user to set a hostid refers to genhostid(1). Genhostid(1) is not available on SUSE Linux. This commit adds a script modeled after genhostid(1) for those users. Zgenhostid checks for an /etc/hostid file; if it does not exist, it creates one and stores a value. If the user has provided a hostid as an argument, that value is used. Otherwise, a random hostid is generated and stored. This differs from the CENTOS 6/7 versions of genhostid, which overwrite the /etc/hostid file even though their manpages state otherwise. A man page for zgenhostid is added. The one for genhostid is in (1), but I put zgenhostid in (8) because I believe it's more appropriate. The mmp tests are modified to use zgenhostid to set the hostid instead of using the spl_hostid module parameter. zgenhostid will not replace an existing /etc/hostid file, so new mmp_clear_hostid calls are required.
