RH 6.1 system with stock kernel 2.2.14-1.1.0 and initscripts-4.91-1 on bootup generates the following message: Machine 1 /var/log/messages.1:Mar 30 17:22:58 kesrith sysctl: error: unable to open preload file '/etc/sysctl.conf' Machine 2 /var/log/messages.1:Mar 30 12:33:59 shonjir sysctl: error: unable to open preload file '/etc/sysctl.conf' Machine 3 /var/log/messages.1:Mar 28 11:44:19 cave sysctl: error: unable to open preload file '/etc/sysctl.conf' While this isnt any kind of show stopper and the entries can still be put in with a script echo blah blah, I am kinda curious.
Update to the latest procps (i.e., the one that shipped with 6.2); there was a bug in the sysctl program.
