Copy comments from the bz:
In rhel7 onwards, we will require dump target filesystem to be mounted in first kernel so that kdump can make use of same mount options instead of trying to come up with its own mount options. This should make mounting that file system safer. Also it reduces complexity in kdump code.
That will mean one needs to put an entry for the dump file system in /etc/fstab
so that after reboot when kdump service starts, it can find the dump target and build initramfs instead of failing.
For raw device upon complex storage such as multipath and iscsi
dracut does not resolve the module dependency automaticlly,
I sent a patch for the device pass via dracut argument "--device"
see below for reference:
http://permalink.gmane.org/gmane.linux.kernel.initramfs/2836
Add --device <device> in mkdumprd for raw dump to fix this issue.
Testing:
raw dump on iscsi targets.

Original host_fs_types could only contain one iscsi slave,
This is due to the check_block_and_slaves will return once the helper function
return TRUE, so only one slave with fs type will be added to host_fs_types[]
Thus, there will no chance to setup other slaves in kdump iscsi setup routine.
Use for_each_host_dev_and_slaves_all to setup all slaves.
Tested by chaowang and myself.

Add two radiobuttons for user to select automatic/manual memory reserve
For fedora they will not be added.
When switching from manual configure to auto reserve, the memory size and
summary widgets will be dimmed.
Testing below cases on virtual machine, all cases need reboot and verify:
Fedora:
1. Enable/Disable kdump
2. change reserve size
3. change kdump.conf content
4. Auto -> Manual
5. Manual -> Auto
RHEL:
modify the /etc/redhat-release and install the rhel7 kernel rpm in fedora vm.
1. auto reservation
2. manual specify reserve mem size
3. enable/disable kdump
4. change kdump.conf content

The '_' before UI string is for Alt+TheFirstCharacter shortkey
ie. Press Alt+T will focus on the self.totalMem widget.
But the totalMem and systemUsableMem are not configurable, so
this is in fact unnecessary. OTOH, The 'Alt+T' will be used in later
patches, so remove these two here.

Copying something from old bug 688150:
Steps to Reproduce:
1.Go through FirstBoot process while get to Kdump
2.Change Kdump memory
3.Press Finish
4.A window pops-up (Changing Kdump setting requires ...)
5.Do not press "No" or "Yes" but pres the "X" in the right up corner.
Actual results:
The effect of this action is the same as pressing "YES"
Expected results:
The effect of this action is the same as pressing "NO
So this patch fix to only reboot when rc == gtk.RESPONSE_YES.
