*kdump* allows a `vmcore` collection without the root file system being mounted
In Red Hat Enterprise Linux 7.4, *kdump* required the root file system to be mounted although this is not always necessary for the collection of a `vmcore` image file. Consequently, *kdump* failed to collect a `vmcore` file if the root device could not be mounted when the dump target was not on the root file system, but, for example, on a usb or on the network. With this enhancement, if the root device is not required for dump, it is not mounted, and a `vmcore` file can be collected.

*** Bug 1467567 has been marked as a duplicate of this bug. *** Hi Dave, I've changed the Doc Text. Can you have a look at it, please? Thanks, Jura Hi, See below comments, other than that it looks good, thanks! >In Red Hat Enterprise Linux 7.4, *kdump* required the root file system to be mounted although this is not necessary for the collection of a `vmcore` image file. "it is not always necessary" is better because when dump target is root then root filesystem is still needed. > Consequently, *kdump* failed to collect a `vmcore` file if the root device could not be mounted because the dump target was located externally, "when the dump target was not root file system" should be better. > for example on a usb or on the network. With this enhancement, if the root device is not required for dump, it is not mounted, and a `vmcore` file can be collected. Hi Dave, I changed the text and hope it's OK now.
