patch to consolidate exit cleanup in mkdumprd none

Description Subhendu Ghosh 2009-01-29 17:19:45 UTC 
Description of problem:
When /etc/kdump.conf contains a target that is not reachable, mkdumprd bails when it tries to create the initrd.

mkdumprd will keep getting invoked every time the system reboots or the kdump service is started/restarted since the kdump.conf timestamp is greater than the kdump-initrd. This causes /tmp to start filling up with incomplete initrd builds.

Version-Release number of selected component (if applicable):
kexec-tools-1.102pre-56.el5_3.1.i386


How reproducible:
Every time

Steps to Reproduce:
1. configure kdump
2. update /etc/kdump with an invalid target
3. after failure - note build remnants in /tmp
  
Actual results:
/tmp contains an incomplete initrd build

Expected results:
incomplete initrd builds should get cleaned out after error logging
