/etc/sysctl.conf is empty


I found that /etc/sysctl.conf is empty in my Centos 5.6.
Should it be like this?

Yes. Any non-standard systend stuff should be in /etc/sysctrl.d/, and the standard things in (or under) /usr/lib/systemd/.

On my Fedora 18 system, the /etc/sysctrl.conf file contains these comment lines:
$ cat /etc/sysctl.conf 
# System default settings live in /usr/lib/sysctl.d/00-system.conf.
# To override those settings, enter new settings here, or in an /etc/sysctl.d/<name>.conf file
# For more information, see sysctl.conf(5) and sysctl.d(5).
Note: Fedora is the Red Hat sponsored free distribution used as a test system for possible RHEL programs, and usually has any non-propitiatory packages that might appear in RHEL releases at some later date. (CENTOS is, as you know, RHEL without RH support, trade marks, and propitiatory packages.)

Oh. when the comment says, e.g., see sysctl.conf(5), it means "run man 5 sysctl.conf in a terminal window."
