Subject: base-files: remove rdate integration, add busybox ntpd init script
and server list in /etc/config/system The rdate applet proved to be too
unreliable to obtain the current time on boot: - public time servers are rare
and often unreachable or overloaded - rdate does not daemonize, it needs a
network connection the moment it is started, leading to race conditions - the
/etc/config/timeserver configuration is overly complex and there is no
reliable way to disable rdate invocations - the time protocol as specified in
RFC 868 is considered obsolete This commit adds an init script
/etc/init.d/sysntpd which starts and stops the busybox ntpd accordingly. The
builtin ntpd can be disabled by either disabling the init script, removing
the symlink to busybox or by clearing the timeserver list in
/etc/config/system.
