It probably doesn't affect many LFSers, but Oracle's RAC installation/ configuration wizard explicitly checks for '-x' in the ntpd options. It does this because you really don't want your database server's time from jumping backwards, and '-x' (or 'tinker step 0' in /etc/ntp.conf) is the only way to guarantee that won't happen. Interestingly, apparently Dovecot doesn't like time going backwards either; I'm sure there are other servers that prefer a uni-directional arrow of time too. For more 'normal' setups, I'd agree that calling 'ntpd -g -q' to do an initial time sync at bootup, followed by ntpd without any other options would be sufficient; the odds that the ntp pool servers most people use are going to jump backwards are so small, I don't think it's worth guarding against by using the '-x' option by default.
