provtest asks the management node the questions a booting node asks and
asserts on the answers. DNS, TFTP and HTTP are driven by dig, curl and
tftp, so the result is what a real client sees rather than what this
tool's own protocol parser believed. The xcatd stages use sockets: they
must choose their source address, because xcatd names a client by the
reverse lookup of the address a connection arrived from.
Scenarios are declarative .conf files sharing dhcptest's assertion
grammar, exit codes and TAP output. Nothing here reads the xCAT database
or runs an xCAT command; every expected value arrives via --set.
validate and list run offline, in a checkout, with no root.
