[Bug 229632] Re: ntpd should run niced

[nutznboltz]

You are supposed to be able to use the -N (--nice) option to ntpd but
upstream ntp bug report shows it doesn't work:

http://bugs.ntp.org/show_bug.cgi?id=1230

Testing on 11.04

$ lsb_release -ds
Ubuntu 11.04
$ uname -srv
Linux 2.6.38-10-generic #46-Ubuntu SMP Tue Jun 28 15:07:17 UTC 2011
$ ntpd --version
ntpd - NTP daemon program - Ver. 4.2.6p2
$ apt-cache policy ntp | egrep 'Installed|Candidate'
  Installed: 1:4.2.6.p2+dfsg-1ubuntu5.1
  Candidate: 1:4.2.6.p2+dfsg-1ubuntu5.1

WIthout -N

$ (ps alx | head -1) ; (ps alx | grep ntpd) | grep -v grep
F   UID   PID  PPID PRI  NI    VSZ   RSS WCHAN  STAT TTY        TIME COMMAND
5   117  1955     1  20   0  38864  2164 poll_s Ss   ?          0:00 /usr/sbin/ntpd -p /var/run/ntpd.pid -g -c /var/lib/ntp/ntp.conf.dhcp -u 117:126

With -N

$ (ps alx | head -1) ; (ps alx | grep ntpd) | grep -v grepF   UID   PID  PPID PRI  NI    VSZ   RSS WCHAN  STAT TTY        TIME COMMAND
5   117  2915     1  20   0  38736  2096 poll_s Ss   ?          0:00 /usr/sbin/ntpd -p /var/run/ntpd.pid -g -N -c /var/lib/ntp/ntp.conf.dhcp -u 117:126

PRI = 20 and NI = 0 in both cases.  If -N did anything NI would not be 0
