The NGDump dracut module is required to build an initramfs image to be used
with NGDump stand-alone dump. NGDump stand-alone dump does not
use a pre-built initramfs image in contrast to SCSI stand-alone dump.
Instead, an initramfs image is built with dracut if NGDump stand-alone dump
is installed on a NVMe partition.
The NGDump dracut module ensures that all necessary tools are present
within the built initramfs and a dump of /proc/vmcore is initiated
to the chosen NVMe partition when the installed dumper is IPLed.
The NGDump dracut module installs a new systemd service and a dump script
into dumper initramfs. The systemd init process starts the NGDump service
at boot shortly after the initialization of the dump target device.
The NGDump systemd service, in its turn, starts the dump script provided
by the new dracut module. The dump script mounts then the dump target
device, creates a copy of /proc/vmcore with the makedumpfile tool on it,
and then shuts down the system.
The NGDump dracut module can be used on any Linux distribution which
supports dracut. But the primary targets are:
- Fedora
- RHEL
- SLES

This change adds a new parameter to the function bootmap_create_file()
that requires the caller to specify a path to the directory where
a bootmap file will be created. The primary motivation for this change is
to support NVMe stand-alone dump, in that case the job's bootmap directory
is not set.

The purpose of this change is to simplify the function bootmap_create(),
make it more readable and prepare for new changes that will follow.
The original function bootmap_create() tried to handle two different cases
and, therefore, contained many conditional statements which had a negative

Until now, NVMe disks were handled by zipl as SCSI disks. To support
NVMe stand-alone dump, it became necessary to further differentiate between
both types of disks.
There are two cases that must be handled:
1. A non-device-mapper device is a NVMe disk if it is assigned to the blkext
device driver.
2. A device-mapper disk is a NVMe disk if the ioctl NVME_IOCTL_ID succeeds.
This case is necessary to properly recognize NVMe disks which are
DM devices and, therefore, not directly handled by the blkext device
driver.
