nouveau-firmware doesn't put third-party firmware in initramfs

One way of getting nvidia devices to work is to load proprietary firmware at boot-time. For this to work, the initial RAM filesystem has to hold firmware files (and kernel has to be booted with parameter
 nouveau.config=NvGrUseFW=1
).

nouveau-firmware needs a initramfs hook that loads files under /lib/firmware/nouveau/ onto the temporary directory.

I think this will work:

/etc/initramfs-tools/hooks/nouveau

#!/bin/sh

PREREQ=""

prereqs()
{
    echo "$PREREQ"
}

case $1 in
prereqs)
    prereqs
    exit 0
    ;;
esac

. /usr/share/initramfs-tools/hook-functions

if test "$verbose" != "n"; then
    cpverbosity="-v"
fi

cp -pr $cpverbosity "/lib/firmware/nouveau" "${DESTDIR}/lib/firmware/"
