Description Martin Milata 2013-07-15 13:19:49 UTC 
As reported in #983017, system-config-kdump is unable to write bootloader configuration on systems that boot using EFI. In addition to fixing s-c-kdump, the SELinux policy needs to be modified to allow s-c-kdump write access to /boot/efi/EFI/fedora/grub.cfg.

It might be relevant that the EFI partition on /boot/efi has FAT32 file system.

Can you also please fix this for F19, or should I open separate bug report?

grep system-config-k /var/log/audit/audit.log

The output of "grep system-config-k /var/log/audit/audit.log" on Fedora 19. (I don't currently have access to EFI-capable machine with F18, sorry.)
Comment 2 Miroslav Grepl 2013-07-16 12:36:19 UTC 
Could you re-test it with

# setenforce 0
# echo "-w /etc/shadow -p w" >> /etc/audit/audit.rules

restart auditd and re-test and run

# ausearch -m avc -ts recent

Attaching requested information.
Comment 4 Daniel Walsh 2013-07-16 17:27:03 UTC 
system-config-kdump should be run with 

#! /usr/bin/python -Es

It should not be using /root/.local.

We should allow it to write to dosfs_t if /boot/efi/EFI/fedora/grub.cfg. is a FAT file system?

I believe that would solve this issue.
