Description Michele Baldessari 2013-12-22 20:42:01 UTC 
Description of problem:
Dec 22 20:28:30 fante systemd: Starting Crash recovery kernel arming...
Dec 22 20:28:32 fante kdumpctl: No kdump initial ramdisk found.
Dec 22 20:28:32 fante kdumpctl: Rebuilding /boot/initramfs-3.12.5-302.fc20.x86_64kdump.img
Dec 22 20:28:47 fante kdumpctl: dracut-install: ERROR: installing '/var/lib/random-seed'
Dec 22 20:28:47 fante kdumpctl: /usr/lib/dracut/dracut-install -D /var/tmp/initramfs.zcIGxX -a /var/lib/random-seed
Dec 22 20:28:47 fante kdumpctl: mkdumprd: failed to make kdump initrd
Dec 22 20:28:47 fante kdumpctl: Starting kdump: [FAILED]
Dec 22 20:28:47 fante systemd: kdump.service: main process exited, code=exited, status=1/FAILURE
Dec 22 20:28:47 fante systemd: Failed to start Crash recovery kernel arming.
Dec 22 20:28:47 fante systemd: Unit kdump.service entered failed state.

On Fedora 20 /var/lib/random-seed does not exist. It is '/var/lib/systemd/random-seed'

Changing the location in the following files, fixed it for me:
/usr/lib/dracut/modules.d/99kdumpbase/kdump.sh:    cat /var/lib/random-seed > /dev/urandom
/usr/lib/dracut/modules.d/99kdumpbase/module-setup.sh:        dracut_install /var/lib/random-seed || exit $?

Version-Release number of selected component (if applicable):
kexec-tools-2.0.4-14.fc20.x86_64

How reproducible:
100%
