Two ways the Subiquity install could fail without saying anything useful. The boot flip read from the install monitor with no timeout. A monitor that accepts the connection and then never answers -- which #7759 shows is a state it gets into -- blocked the read forever, and with it the Subiquity late-command and the install. The retry loop could not help: it never reached the retry. Both reads now take -t 10, so five attempts are bounded at roughly two minutes and end in the failure that is already logged. The regression test stands up a listener that accepts and holds the connection; removing the timeouts fails it. mkinstall resolved the install server for nfsroot and fell back to the name when that failed: "getipaddr($instserver) || $instserver". The name is the original defect -- klibc's nfsmount cannot resolve one -- so the node panicked "can't parse IP address" at boot, on the node, with nothing reported on the management node. The management node knows at template time, so it says so there and skips the node, as the other unrecoverable per-node conditions in this routine do.
