copytree() recursively copies the contents of SRC into DEST.
If DEST doesn't exist it is created; if it exists the contents of SRC
get merged into it (duplicate files are overwritten).
rd.neednet could be removed, as we can check /tmp/net.ifaces.
After this patch, kdump can bring up the NIC without
rd.neednet.

live.updates allows you to specify the URL for an "updates image" that
should be applied to the live runtime before switch_root.
The URL can be anything supported by url-lib (http, https, ftp, possibly
nfs) and the image can be anything supported by img-lib (xz/gzip
compressed cpio/tar, uncompressed cpio/tar, filesystem image, etc.)
This makes the livenetroot module use url-lib for fetching its root
image/filesystem. There's also some minor tweaks for POSIX compliance.

The livenet module allows you to use a root arg like:
root=live:http://server.name/path/to/live.img ip=dhcp
The named live image will be downloaded with wget and then set up as the
root device.
It currently supports FTP, HTTP, and HTTPS. dracut will try to install
the CA bundle (/etc/ssl/certs/ca-bundle.crt) into the initramfs so that
SSL certificate checking will work properly.
If an HTTPS URL is given and the site fails the certificate check, the
file will be rejected and the system will not boot into it.
