linux-boot: Ensure /etc exists on the root file system.
Fixes a regression introduced in
c828969036 whereby /etc would no longer be
created as a result of calling 'mark-as-not-killable'.

This would affect ISO images because 'make-iso9660-image' does not
create /etc by default.  In particular, the ISO installation image as
created by the "iso-image-installer" test would fail to boot while
creating the /root/etc/mtab symlink:
<https://hydra.gnu.org/build/2352514/nixlog/9/raw>.

* gnu/build/linux-boot.scm (mount-root-file-system): Make sure /root/etc
exists.

Hartmut Goebel c828969036
build: Use overlayfs instead of unionfs.
Overlayfs is part of the kernel, while unionfs needs FUSE.  This also reduces
the size of the initrd by ca. 4.3% (487K).

* gnu/build/linux-boot.scm (mount-root-file-system): Remove optional parameter
  "unionfs"; mount using overlayfs instead of unionfs; new directory layout
  requied by overlayfs; update documentation.
  [mark-as-not-killable]: Remove now unused function

* gnu/system/linux-initrd.scm (file-system-packages): Remove now unused
  packages "unionfs-fuse/static" and thus unused related 'if'.
  (linux-modules): Replace "fuse" by "overlay".

file-systems: 'mount-file-system' now takes a <file-system> object.
* gnu/build/file-systems.scm (mount-file-system): Rename 'spec' to 'fs'
and assume it's a <file-system>.
* gnu/build/linux-boot.scm (boot-system): Assume MOUNTS is a list of
<file-system> and adjust accordingly.
* gnu/build/linux-container.scm (mount-file-systems): Remove
'file-system->spec' call.
* gnu/services/base.scm (file-system-shepherd-service): Add
'spec->file-system' call.  Add (gnu system file-systems) to 'modules'.
* gnu/system/linux-initrd.scm (raw-initrd): Use (gnu system
file-systems).  Add 'spec->file-system' call for #:mounts.

build: Fix compilation warnings.
* gnu/build/linux-boot.scm (define-module): Use (guix build syscalls).
* gnu/build/linux-modules.scm (define-module): Ditto.
* gnu/build/file-systems (define-module): Stop re-exporting mount, umount and
MS_* flags as this is now safe to include (guix build syscalls) instead.
(mount): Remove procedure.
(umount): Ditto.

  "/etc/shepherd/do-not-kill".
* gnu/build/linux-boot.scm (mount-root-file-system): Rename

'mmap'.

Ludovic Courtès cc0e575a94 linux-boot: Mount /dev as a devtmpfs from the start.
Suggested by Petter <petter@mykolab.ch>
and Mark H Weaver <mhw@netris.org>.
Reported by Duncan Keall <duncan@duncankeall.com>.

Partly fixes <http://bugs.gnu.org/19190> by populating /dev/mapper
early enough.

  a devtmpfs.
  (move-essential-file-systems): Add /dev.
  (mount-root-file-system): Mount /rw-root/dev as a devtmpfs instead of
  calling 'make-essential-device-nodes'.
  (boot-system): Remove call to 'make-essential-device-nodes'.
* gnu/system/file-systems.scm (%devtmpfs-file-system): Remove.
* doc/guix.texi (File Systems): Adjust accordingly.

Ludovic Courtès 01ed3c4fe5 linux-boot: Don't fail if /root/etc/mtab is a dangling symlink.
Reported Joshua Grant.
Patch suggested by Mark H Weaver.

* gnu/build/linux-boot.scm (mount-root-file-system): Use
  'false-if-exception' instead of 'when (file-exists? ...)' to account
  for dangling symlinks.

* gnu/build/linux-boot.scm (mount-root-file-system): Make /root/etc/mtab
  a symlink to /proc/self/mounts.
* gnu/build/file-systems.scm (mount-file-system): Don't update /etc/mtab.

  (load-linux-module*): Remove.
  (boot-system): Add #:linux-module-directory parameter.
  [lookup-module]: New procedure.
  Call 'current-module-debugging-port'.  Pass #:lookup-module to
  'load-linux-module*'.  Map LOOKUP-MODULE on LINUX-MODULES.
* gnu/system/linux-initrd.scm (base-initrd): Adjust 'boot-system' call
  accordingly.  Adjust #:modules argument as well.
* gnu/system.scm (operating-system-activation-script)[%modules]: Likewise.

Partly fixes <http://bugs.gnu.org/19190>.
Reported by Nikita Karetnikov <nikita@karetnikov.org>.

* gnu/build/linux-boot.scm (boot-system): Move PRE-MOUNT call before
  'mount-root-file-system' is called.

* gnu/build/linux-boot.scm (mount-root-file-system): Remove 'catch #t'
  around body.  This was unneeded and even inconvenient because this
  procedure is called from within 'call-with-error-handling' already.

  honor it.

Ludovic Courtès 42d10464be linux-initrd: Store Linux modules in a normal store directory.
* gnu/system/linux-initrd.scm (expression->initrd): Remove #:linux and
  #:linux-modules parameters.  Remove call to
  'float-linux-module-directory'.
  (base-initrd): Add call to 'float-linux-module-directory'.  Use it in
  #:linux-modules argument in the gexp.  Remove #:linux and
  #:linux-modules arguments to 'expression->initrd'.

  #:linux-module-directory parameter.  Don't create 'modules'
  sub-directory.

  LINUX-MODULES.
* doc/guix.texi (Initial RAM Disk): Adjust accordingly.

Ludovic Courtès 70608adb4a linux-initrd: Copy all the script's closure to the initrd.
* gnu/system/linux-initrd.scm (expression->initrd): Remove calls to
  'imported-modules' and 'compiled-modules'.  Use 'gexp->script' with
  EXP.  Add the result to TO-COPY.  Make /init a symlink to that script,
  and copy its closure into the "contents" directory.  Add fake
  /proc/self/exe symlink.
* gnu/build/linux-boot.scm (load-linux-module*): Add comment about mmap.
* gnu/system/vm.scm (system-qemu-image/shared-store-script): Add "-m
  256".  This turns out to be needed for initrds containing things like
  e2fsck and several modules; with the default of 128 MiB, loading
  libahci.ko may fail with -1.
