shutdown shows the message /etc/rc6.d/killall /etc/init.d/powertweak no such file or directory This is because the file in /etc/init.d is called powertweakd but the execution of /etc/init.d/pvmd touches the file /var/lock/subsys/powertweak killall strips the directory part from the entry in /var/lock/subsys/powertweak and tries execute the file in /etc/init.d/powertweak which does not exist
We (Red Hat) should really try to fix this before next release.
OK. This is fixed in the powertweak-0.99.0-5 derived packages. It has been fixed by having the initscript touch /var/lock/subsys/powertweakd instead of /var/lock/subsys/powertweak. Thanks for the heads up. Tim
