netbsd-iscsi is not available on RHEL
Beef up the testsuite to use the two targets over different
interfaces.
Test the new iSCSI parameters rd.iscsi.waitnet and rd.iscsi.testroute.
Debian based distros use dhcpd3 instead of just dhcpd. Accordingly
paths to lease files etc are different as well. This patch ensures
that the test-suite can run with either dhcpd or dhcpd3.
With this change, we can now use LUKS and LVM over NBD. There are
some decisions to be made regarding where we should get the fstype
and fsoptions from (DHCP root vs rootfstype= etc), but the basic
functionality is there.
