# If KDUMP_DUMPDEV points to a device file, the dump is written to that device
# when booting from the kdump kernel. The advantage over is that you don't have to
# mount the root file system (which may be corrupted!) just to write the
# dump. On the first normal boot which is able to succesfully mount the
# root file system, the dump is saved to KDUMP_SAVEDIR as usual.
#
# Important: The KDUMP_DUMPDEV is overwritten by kdump, so don't use it for
# saving any data. Also don't use the currently used swap partition.
