guile-static-stripped now takes a string for the 'options' argument, just like
the 'mount' procedure in (guix build syscalls).

at <http://lists.gnu.org/archive/html/guix-devel/2015-04/msg00229.html>.
* gnu/build/install.scm (populate-single-profile-directory): New procedure.
* gnu/system/install.scm (self-contained-tarball): New procedure.
* Makefile.am (guix-binary.%.tar.xz): New target.
Fixes <http://bugs.gnu.org/19795>.
Reported by David Thompson <dthompson2@worcester.edu>.
* gnu/build/activation.scm (enumerate, current-users, current-groups,
delete-user, delete-group): New procedures.
(activate-users+groups): Add calls to 'delete-user' and
'delete-group'.
* doc/guix.texi (User Accounts): Add a paragraph about statelessness.
Explain that passwords are preserved.
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/activation.scm (%skeleton-directory): New variable.
(dot-or-dot-dot?, copy-account-skeletons): New procedure.
(add-user): Use 'copy-account-skeletons'.
(activate-etc): Use 'dot-or-dot-dot?'.
This would not work when /boot is a separate partition, as reported by
Nikita Karetnikov <nikita@karetnikov.org> in <http://bugs.gnu.org/19220>.
This fixes a regression introduced in 39d1f82.
* gnu/build/install.scm (install-grub): Copy GRUB.CFG instead of
symlinking it, as was the case before 39d1f82.
* gnu/build/vm.scm (register-grub.cfg-root): Add 'grub.cfg' parameter.
Make it a permanent GC root instead of an indirect GC root.
(initialize-hard-disk): Adjust accordingly.
* guix/scripts/system.scm (install-grub*): Replace use of
'add-indirect-root' by the addition of a permanent GC root in
%GC-ROOTS-DIRECTORY.
Fixes <http://bugs.gnu.org/19160>.
* guix/scripts/system.scm (install-grub*): Make /boot/grub/grub.cfg an
indirect GC root.
* gnu/build/install.scm (install-grub): Make TARGET a symlink.
* gnu/build/vm.scm (register-grub.cfg-root): New procedure.
(initialize-hard-disk): Use it.
* gnu/packages/patches/guile-linux-syscalls.patch (scm_load_linux_module):
Leave 'errno' unchanged when ERR != 0.
* gnu/build/linux-modules.scm (load-linux-module*): Check for the errno
value of ARGS to determine whether the module was already loaded.
* 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.
* gnu/build/file-systems.scm (mount-file-system): When OPTIONS is false,
write "rw" to /etc/mtab. This fixes a bug whereby 'remove-from-mtab'
in (guix syscalls) would otherwise raise a 'match-error' because of
the missing field. This affected file systems mounted from the
initrd, such as devtmpfs, which has options == #f.
Reported by nebuli on #guix.
* gnu/build/vm.scm (initialize-partition-table): Add #:bootable?
parameter and honor it.
(initialize-hard-disk): Likewise.

'activate-firmware'.
* doc/guix.texi (operating-system Reference): Document 'firmware'.
Fixes <http://bugs.gnu.org/18525>.
Reported by Mark H Weaver <mhw@netris.org>.
* gnu/build/activation.scm (activate-modprobe): New procedure.
* gnu/system.scm (modprobe-wrapper): New procedure.
(operating-system-activation-script): Use both.
* gnu/build/linux-boot.scm (boot-system): Add #:pre-mount parameter and
honor it.
* gnu/system/linux-initrd.scm (base-initrd): Add #:mapped-devices
parameter. Add 'device-mapping-commands' variable, and use it to
build the #:pre-mount argument of 'boot-system'.
* gnu/system.scm (mapped-device-user,
operating-system-user-mapped-devices,
operating-system-boot-mapped-devices): New procedures.
(device-mapping-services): Use 'operating-system-user-mapped-devices'
instead of 'operating-system-mapped-devices'.
(operating-system-initrd-file): Call the initrd with #:mapped-devices.
* gnu/build/activation.scm (activate-current-system): Honor
$GUIX_NEW_SYSTEM by default.
* guix/scripts/system.scm (switch-to-system): Set $GUIX_NEW_SYSTEM
before loading SCRIPT.
* gnu/build/install.scm (directives): Remove "/bin/sh".
* gnu/build/activation.scm (activate-/bin/sh): New procedure.
* gnu/system.scm (operating-system-activation-script): Use it.
Before that, 'sudo' would exit with:
sudo: /etc/sudoers is not a regular file
sudo: no valid sudoers sources found, quitting
* gnu/build/activation.scm (activate-etc): Check if SOURCE matches
'file-is-directory?'. If not, use 'copy-file' instead of 'symlink'.
