We've been finding cases where multiple instances of dracut can be launched
simultaneously, resulting in a corrupted initramfs file. This patch makes
dracut write the initramfs to a new file, then move it into place atomically.
/usr/lib/dracut/dracut.conf.d/*.conf can be overwritten by the same
filenames in /etc/dracut.conf.d.
Packages should use /usr/lib/dracut/dracut.conf.d rather than
/etc/dracut.conf.d. /etc/dracut.conf.d belongs to the system
administrator.
This also changes the command line switch to be --add-device and the
config directive is set to add_device. This was chosen as device= in the
config file seems too generic and not quite as consistent with other
directives (i.e. drivers/add_drivers)
The --device command line is still supported but it should be considered
deprecated in favour of --add-device.
Kdump support dump to raw device which could be on top of complex storage
such as multipath and iscsi which are standalone dracut modules.
Add a --device option to dracut which will add the device to host_devs so
dracut can add the dependent modules automaticlly and enable them in initramfs.
--device will accept device node name as the param.

each dev in host_devs[] should be waited in initqueue to make sure they
are oneline before initqueue finish.
Add a new wait_host_devs.sh in base module to make this a generic thing.
Because all the devs in fstab lines are also added to host_devs, so no need
do same wait in fstab-sys module anymore.
[v2->v3]: do not add slave devices to host_devs
wait for persistent dev name in initramfs

We do not want to install dracut-install to /usr/bin until all
interfaces are set to stone and the manpage is written. Until then the
tool is dracut internal.
First, we just install the kernel module and keep track, what we
installed. At the very end, call modprobe and modinfo for firmwares to
resolve all kernel module dependencies. This speeds up image creation,
because we can call modprobe and modinfo with many modules.
