variable. Use 'mount-root-file-system' and 'mount-file-system'.

declaration.
* guix/build/linux-initrd.scm (make-essential-device-nodes): Make
/dev/fuse.
(boot-system): Add #:unionfs parameter. Invoke UNIONFS instead of
copying files over when VOLATILE-ROOT? is true.
* gnu/system/linux-initrd.scm (expression->initrd): Add #:inputs
parameter.
[files-to-copy]: New procedure.
[builder]: Add 'to-copy' parameter; honor it.
(qemu-initrd)[linux-modules]: Add 'fuse.ko' when VOLATILE-ROOT?.
Pass UNIONFS-FUSE/STATIC as #:inputs; change builder to pass #:unionfs
to 'boot-system'.

variable.
[linux-modules]: Append VIRTIO-9P-MODULES when a 9p file system is in
MOUNTS.

(boot-system): Recognize '9p' in MOUNTS, and use 'mount-qemu-9p'.
* guix/build/linux-initrd.scm (make-essential-device-nodes): Rename
devices with major = 8 to /dev/sda*. Make /dev/vda* devices.
* gnu/system/vm.scm (qemu-image): Change '/dev/vda' to '/dev/sda'.

* guix/build/linux-initrd.scm (boot-system): New procedure.
* gnu/system/linux-initrd.scm (qemu-initrd): Add keyword parameters
'guile-modules-in-chroot?' and 'mounts'. Change builder to simply
call 'boot-system'.
(gnu-system-initrd): Change to a simple call to 'qemu-initrd'.
* gnu/system/vm.scm (expression->derivation-in-linux-vm): Call
'qemu-initrd' with #:guile-modules-in-chroot?.
* gnu/packages/linux-initrd.scm (qemu-initrd): Add (guix build utils) to
#:modules, and use it. Copy .scm and .go files to /root.
* guix/build/linux-initrd.scm (bind-mount): New procedure.
