loginstall specifies a directory, in which dracut-install records all
files, which were installed from the host system to the initramfs.
Use case is e.g. to create a list of packages to watch for updates, to
maybe trigger a recreation of the initramfs.
Which will not only add listed drivers, but also enforce that they are
tried to be loaded at early boot time.
This is needed if drivers which are not autoloaded (e.g. loop and a lot
others) shall get loaded via initramfs.
Otherwise dracut-logger.sh outputs an empty version on journal testing.

This patch adds bittorrent support to 45url-lib for those that might want
to retrieve the same live image for multiple systems at once without
saturating the network.
This patch requires ctorrent to be installed into initramfs.
Torrent kernel command line format:
root=live:torrent://example.com/liveboot.img.torrent
Start a tracker:
bttrack --bind <tracker_ip> --port 6969 --dfile dstate --reannounce_interval 60
Create the torrent:
ctorrent -t live_image -u http://<tracker_ip>:6969/announce -s live_image.torrent
Seed the initial torrent:
ctorrent live_image.torrent
Boot the live image.
A user can provide a filesystem image (rootfs.img) inside a compressed
tarball and that filesystem image will be mounted read/write. This provides
some benefits over a device mapper snapshot overlay, especially when the
live system becomes full. The boot command line simple needs
"rd.writable.fsimg" added to utilize this feature.
Additional documentation for this option as well as other live boot
options is included.

With the same source of files, it should be possible to generate the
same image file with every dracut run.
To accomplish this, we modify the timestamps of the files we generate at
runtime, call gzip with "-n" and cpio with "--reproducible".
The cpio --reproducible option is not yet upstream though, so if you
feel like it should be then please nag at the cpio mailing list.

In case of raw disk/partition, ex. /dev/vda1, which doesn't contain any
filesystem on it. get_persistent_dev() would return empty. Now fix it to
return its original name, /dev/vda1 in above case. So that we don't have
to check its return string every time.

DRACUT_PATH can now be used to specify the PATH used by dracut
to search for binaries instead of the default
/usr/sbin:/sbin:/usr/bin:/bin
This should be set in the distribution config file
/usr/lib/dracut/dracut.conf.d/01-dist.conf
because some inst*() functions check the existance of the source files
and do not know about the "-H" option, some failed to install the
hostonly files.
