I managed to run ntpdate at a high priority. My initial thought is to use nice command, like:
nice -n -10 ntpdate -p 8 -u $NTP_TIME_SERVER
However, after checking the nice value of ntpdate command, it stays at -12, regardless of nice -n command.
Did anyone have same experience of modifying priority of ntpdate before? How can I configure ntpdate to make it work at a high priority? Thanks in advance. :-)
