makentp reads site.ntpbackend to pick the NTP daemon, so an admin has to set it, but the
attribute appears in no help text. lsdef -t site -h and tabdump -d print the site table
description from xCAT::Schema, which documents site.dhcpbackend and says nothing about
ntpbackend. The makentp man page lists the site attributes the command honors and does not
list it either.
The selector test now reads the site help from the loaded schema and the makentp pod.
Five assertions fail: the attribute name, its three valid values, and the man page entry.

xCAT::NTP::Backend->available reports chrony as available when chronyd exists. makentp
configures chrony only when systemctl exists as well, and setupntp hands over to ntpd without
it. On a host with chronyd and no systemctl the selector answers chrony, makentp takes the ntpd
path anyway, and the admin is told nothing.
ntp_backend_selection.t drives available and choose with the command probe injected, so a case
can hold chronyd present and systemctl absent without depending on what the test host has
installed.
Six assertions fail: available reports chrony on chronyd alone, and choose neither downgrades
nor asks for an install.

An xCAT management node must serve time to its compute nodes (they point at
ntpservers=<xcatmaster>). Ubuntu ships only systemd-timesyncd, an SNTP client that
disciplines the local clock but cannot serve time, and makentp supports chronyd and
ntpd only. On a stock Ubuntu MN makentp therefore fails outright with "Please make
sure ntpd is installed", reddening reg_linux_diskfull_installation_flat.
Two further defects compound it. setupntp hard-requires hwclock through
check_exec_or_exit, but Ubuntu 24.04 moved hwclock into util-linux-extra, which is
absent from minimal images -- so the whole NTP setup, including the clock step that
does not need hwclock at all, aborts. And systemd-timesyncd is part of systemd rather
than a time-daemon package, so it coexists at the package level and keeps disciplining
the clock against whichever daemon xCAT just configured.
Assert a shared, unit-tested daemon selector in the spirit of xCAT::DHCP::Backend, the
package dependencies that guarantee a server-capable daemon and hwclock, and the
setupntp changes. All fail today.
