Current status

  • Targeted release: Fedora 16
  • Last updated: 2011-07-11
  • Percentage of completion: 10%


  • Dump to local filesystem


  • Read /etc/kdump.conf to generate initrd
  • Dump to remote host via ssh
  • Dump to remote host via nfs
  • Dump to raw block device
  • Implement full functionality of /etc/kdump.conf
  • Dump to multiple targets

Detailed Description

Currently in kexec-tools we use our own /sbin/mkdumprd to generate an initrd for kdump kernel. However, due to the natural complexity of making a new initrd, we have lots of burdens to maintain the mkdumprd code, we decide to switch to using dracut to generate kdump initrd. And hopefully, we can provide a distro-independent mkdumprd to upstream, as dracut itself is cross-distribution.

Benefit to Fedora

The main source of kexec-tools bugs is in mkdumprd, with this change, hopefully we will reduce the number of bugs of kexec-tools.


All functionality of /sbin/mkdumprd has to be implemented and tested in this new mkdumprd.
