Description of problem:

configfiles /etc/sysconfig/mkinitrd/* must be executable to be sourced in by /sbin/mkinitrd which is not necessary. they will be silently ignored if they are not executable.

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

5.1.19.6-71.el5_7.1

How reproducible:

always

Steps to Reproduce:
1.disable building ramdisk with DMRAID by creating a file /etc/sysconfig/mkinitrd/dmraid with content "DMRAID=no" and permissions 644
2.create a ramdisk. mkinitrd will try to find all dmraid devices which can take a lot of time in SAN-environments.
3.
  
Actual results:

mkinitrd tries to detect dmraid devices even with DMRAID=no

Expected results:

mkinitrd ignores dmraid devices if DMRAID=no specified

Additional info:

fix is trivial, just check for readable instead of executable:
