Description of problem:

yum update to acpid-1.0.4-9.el5_4.1 fail leaving two acpid versions in ssytem if acpid is not running (that is if there is no /var/log/acpid* files).

Version-Release number of selected component (if applicable):

1.0.4-9.el5_4.1

How reproducible:

Always.

Steps to Reproduce:
1. yum update
  
Actual results:

error: %trigger(acpid-1.0.4-9.el5_4.1.x86_64) scriptlet failed
exit status 1

Both old and new acpid versions installed on system,


Expected results:

Successful update.


Additional info:

This happens every time if acpid was not running on system (like on xen virtual host).

$ rpm -q --triggers acpid
triggerin scriptlet (using /bin/sh) -- acpid <= 1.0.4-9.el5_4.1
[ -f /var/log/acpid ] && chmod 0644 /var/log/acpid*

It's quite obvious why this script is giving error when /var/log/acpid file is not there. I suggest following scriptlet instead:

if [ -f /var/log/acpid ]; then
    chmod 0644 /var/log/acpid*
