We will still expect target to be mounted in first kernel. Just that
one should be able to only specify path and it is not mandatory to
specify disk too.
For example, say you have mounted a disk /dev/sdb on /mnt/foo. And say
you wanted dump to be saved in foo1 directory on disk sdb.
So far one will have to say following in /etc/kdump.conf to achive above.
Now one should be able to achieve same goal by specifying.
Kdump script will recognize that a disk is mounted on /mnt/foo and
internally it will come up with target=/dev/sdb and path=/foo1.
So something which had to be done explicitly by user and now also
be done by kdump script. User just has to pass full path of where dump
needs to be saved.

I think so. After this change, one should be able to change path even if
target is not specified. Some kind of error checking would be good though
to make sure path specified by user does exist.
Nice, thanks for the explanation. I'm wondering whether s-c-kdump needs
to know if the current kexec-tools support this feature. If we simply
allow the path to be supplied regardless of kexec-tools version, the
worst that can happen is that kdump.conf is generated which causes (an
old version of) kdump to save the dump on root fs in the specified
directory. Is that acceptable?

We just need to make sure path exists.

This is fedora specific list so let us limit discussion to fedora only. We
want to make this change in fedora because people have separate disk
mounted in on /var and they expect dump to show up there automatically.
I think it will also make the configuraiton easier.
Ah, sorry, should have looked at the name of the list.
