What if user decides do dump to root partition (even if there is another
disk mounted on /var). I think we should have mechanism to address that.
I see that "path" is uncommented in kdump.conf. So kdump code has to
assume that user specified it.
But disk is not uncommented and we take rootfs as default.
So we can do following.
- If dump target is specified in kdump.conf, then just dump to it. User
wants it that way.
- If dump target is not mentioned in kdump.conf and are dumping to rootfs
by default, in that case we need to check whether there are other disks
mounted in "path" and fail service.
The example you gave, yes, there kdump service will fail as user has not
specified the disk and there is another disk mounted on /home/user/test
path.
Yeah, can't agree more. Thanks for making this clear.
Thanks
Vivek
