I checked kerneld tries load modules or reread conf file many times executing modprobe and command from config like this: path[*]=/lib/modules/`uname -r` path[*]=/lib/modules/`kernelversion` On my station invocation of ifconfig execute about 160 processes: > 22:06:59 3:2'[EMAIL PROTECTED] ifconfig >/dev/null;ps tp3 > PID TTY STAT TIME COMMAND > 15329 p3 S 0:00 /bin/bash > 22506 p3 R 0:00 ps tp3 > 22:09:58 3:2'[EMAIL PROTECTED] ifconfig >/dev/null;ps tp3 > PID TTY STAT TIME COMMAND > 15329 p3 S 0:00 /bin/bash > 22672 p3 R 0:00 ps tp3 22672-22506 = 166 !!!!!!!! Bug should be posted against modutils: $ time ifconfig real 0m4.923s :( user 0m0.020s sys 0m0.000s $ killall kerneld !!!! $ time ifconfig real 0m0.034s :) user 0m0.010s sys 0m0.000s Mirek
