Description Dave Young 2012-06-18 22:04:46 EDT
I guess this related to selinux policy, please help to take a look:

kdump.service 1st time startup will fail with below info
Jun 12 23:28:39 localhost kdumpctl[548]: + ldconfig -r
Jun 12 23:28:39 localhost kdumpctl[548]: ldconfig: Can't create
temporary cache file /etc/ld.so.cache~: Permission denied

dracut ran cmd like: 'ldconfig -r /var/tmp/foo' in kdump.service

I'm seeing below selinux audit log:

type=AVC msg=audit(1340070736.339:41): avc:  denied  { read } for  pid=4493 comm="ldconfig" name="lib64" dev="dm-1" ino=2684 scontext=system_u:system_r:ldconfig_t:s0 tcontext=system_u:object_r:initrc_tmp_t:s0 tclass=dir

Comment 1 Fedora End Of Life 2013-07-03 20:50:36 EDT
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '17'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 17's end of life.

Bug Reporter:  Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 17 is end of life. If you 
would still like  to see this bug fixed and are able to reproduce it 
against a later version  of Fedora, you are encouraged  change the 
'version' to a later Fedora version prior to Fedora 17's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Looks like you have a major labelling problem.

restorecon -R -v /etc

You might want to 

touch /.autorelabel; reboot
