is is a little redundent, can be optimized into one line. For nfs/ssh,
this line of code is enough.

Currently the gtk spinbox use 64M as the spin step size, this means user
can only reserve memsize round down to 64M. But in fact user can simply
input the value which is not aligned to step size in the text entry. Also
user can use any value from kernel boot cmdline. Thus it will cause problem:
For example, booting with crashkernel=138M, firstboot spinbox will round down
it to 128M, and show 128M in spinbox value, but actualy reserved label will
show 138M, they are not consistent and confusing.
We have lowerBound value which is 128M, there's no reason to limit the increase
step as 64M, fix this by changeing the step to 1M.
Tested with fedora 18 for different values.

We need fs dump target being mounted firstly before creating mkdumprd
This is because we want to get the mount options from kernel mountinfo
instead of simply mount it without considering mount options.
To avoid the filesystem being used by something other than kdump we
suggest them to mount it as 'ro', mkdumprd will remount it as 'rw' when
necessary and remount it back to 'ro'
In 2nd kernel kdump will still use 'rw' to mount it though.
Tested local read-only mounted fs dump.
[v1->v2]: improve documentation

Old po/ folder are not well maintained. All po files are just
same as the outdated pot file.
Translating team need kexec-tools to update it to
the conventional mode so it become available for translating.
Currently old translated po files are not maintained in git.
Instead it's a kexec-tools-po.tar.gz in dist git server.
see kexec-tools.spec: Source13. This patch will maintain them
in po/ and update the contents from lastest source code.
The refresh include below items:
1. update pot file from latest source code.
2. merge old translated po files with the new pot file
3. maintain translated po files in po/ folder
Also updated the Makefile to make the process more easier.
Usage after the update is like below:
a) simple `make` will generate the mo files for installation
b) `make install` will install mo files to locale directory
Above two command are used in rpm spec to install mo files
c) `make merge` will update pot file from source code and merge
translated po files with latest pot file. So it become ready for
translation team to translate
For kexec-tools maintaining, what we need to do is:
Once firstboot_kdump.py is modifed, we should run `make merge`
to update the po files for translation
After po files get translated they need to be copied to po/
and commit to git. Then create a kexec-tools-po.tar.gz and
upload the tar.gz to dist git, also update the checksum in spec
file.
Kdump systemd service should be enabled after installation like what
we do for old sysv init service.
systemctl enable will do daemon-reload automaticlly, so no need to
reload the daemon again. Please see manpage of systemctl about the detail.

MEM_RESERVED is for checking if crash memory is reserved or not.
Originally it use /proc/iomem for x86, parsing /proc/cmdline for ppc.
This cause problems for crashkernel=auto, because it does not fit for

Fix this by use /sys/kernel/kexec_crash_size for all arches.

ssh will send local stdin input to remote side, this cause trouble
when we call ssh in the loop of parsing kdump.conf.
Ie. if we specify both 'ssh' and 'core_collector' option in kdump.conf,
and put 'core_collector' behind 'ssh', there will be no chance to
handle 'core_collector' because in get_ssh_size() ssh eat all the later
input of the while loop.
Fix this by use /dev/null as stdin in get_ssh_size().

For devices with filesystem, udev /dev/disk/by-uuid/* links are usually
reliable. But one exception is multipath devices, child and top layer
device may have same uuid.
As dm devices maintain /dev/mapper/* as persistent names, so converting to
/dev/mapper/* firstly then try by-uuid/* and by-id/*
Also because user know better what's the persistent name we just document well
to suggest user use persistent name in kdump.conf. it's suggested to
to use lvm or multipath canonical names or uuid/label.

vmcore-dmesg: Do not write beyond end of buffer
scan_vmcoreinfo() currently assumes that every vmcoreinfo note line ends
with \n and overwrites new line with \0. But last entry in note, CRASHTIME=
does not end with \n and this leads to corrupting memory as we write beyond
end of buffer.
Normally things were fine but when I added some fields to vmcoreinfo, this
bug started showing and vmcore-dmesg started crashing.
I am planning to send a patch to fix this in kernel but it might be good
idea to handle this case in user space too so that vmcore-dmesg works
fine with cores of older kernels.

vmcore-dmesg: vmcore-dmesg: Make it work with new structured logging format
Now kernel has made kernel logging structured and exsisting vmcore-dmesg
does not work with this new format. Hence kernel version 3.5 is broken. In
3.6 now a kernel patch has been put which exports relevant fields. This
patch parses those fields and makes vmcore-dmesg work with new logging
format.
Currently it does not display log levels or dictionary. I personally think
that log levels are not very useful and it also requires additional kernel
patches so that log levels are not bitfields and relevant information is
exported to user space properly.
Concept of dictionary is new and relevant information is exported. One can
possibly enahnce vmcore-dmesg to also print dictionary contents based on
a user command line option.

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:
