* gnu/build/file-systems.scm (read-ext2-superblock*, partition-predicate): New
procedures.
(partition-label-predicate): Rewrite in terms of 'partition-predicate'.
(partition-uuid-predicate, find-partition-by-uuid, uuid->string): New
procedures.
(%network-byte-order): New macro.
(canonicalize-device-spec)[canonical-title]: Check whether SPEC is a string.
[resolve]: New procedure.
Add 'uuid' case and use it.
* gnu/build/linux-container.scm: New file.
* gnu-system.am (GNU_SYSTEM_MODULES): Add it.
* .dir-locals.el: Add Scheme indent rules for 'call-with-container', and
'container-excursion'.
* tests/containers.scm: New file.
* Makefile.am (SCM_TESTS): Add it.
* gnu/build/file-systems.scm: Import (guix build syscalls) when 'mount' is not
defined.
* gnu/system.scm (operating-system-activation-script): Include (guix build
syscalls) module in derivation.
* gnu/build/linux-initrd.scm (write-cpio-archive): Remove 'open-pipe*' and
related calls. Compute list of files in 'files' variable. Use
'cpio:write-cpio-archive'. Remove #:cpio parameter.
(build-initrd): Remove #:cpio parameter.
* gnu/system/linux-initrd.scm (expression->initrd): Likewise, and adjust
BUILDER accordingly. Add (guix cpio) to #:modules.
Rather than expecting a pointer, the version of 'mount' in
guile-static-stripped now takes a string for the 'options' argument, just like
the 'mount' procedure in (guix build syscalls).
* gnu/packages/patches/guile-linux-syscalls.patch (mount): Expect a string or
#f for 'options' argument.
* gnu/build/file-systems.scm (mount-file-system): Use new 'mount' interface.
* gnu/build/install.scm (populate-root-file-system): Delete system-1-link
under TARGET, not under /. Use 'catch' and check for EEXIST instead of
(false-if-exception (delete-file ...)).
* gnu/build/file-systems.scm (MS_REMOUNT): New constant.
(mount-file-system): Add 'flags' local variable. When FLAGS has
MS_BIND & MS_RDONLY, call 'mount' with MS_REMOUNT.
* gnu/services/base.scm (file-system-service) <start>: Likewise.

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.
* gnu/build/activation.scm (activate-firmware): New procedure.
* gnu/system.scm (<operating-system>)[firmware]: New field.
(directory-union): New procedure.
(%base-firmware): New variable.
(operating-system-activation-script): Use 'directory-union', and call
'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'.
* gnu/build/install.scm (evaluate-populate-directive): Wrap body in
"catch 'system-error", and report clear errors. In the symlink case,
retry up EEXIST.
(populate-root-file-system): Remove /var/guix/profiles/system-1-link
before attempting to create it.
* 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'.
* gnu/build/linux-initrd.scm (build-initrd): Remove
#:linux-module-directory parameter. Don't create 'modules'
sub-directory.
* gnu/build/linux-boot.scm (boot-system): Mentin that LINUX-MODULES is a
list of absolute file names. Don't prepend "/modules/" to
LINUX-MODULES.
* doc/guix.texi (Initial RAM Disk): Adjust accordingly.
* gnu/build/linux-initrd.scm (cache-compiled-file-name,
compile-to-cache, build-initrd): New procedures.
* gnu/system/linux-initrd.scm (expression->initrd)[builder]: Remove code
now moved above. Use 'build-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.
* gnu/build/linux-initrd.scm: New file.
* gnu-system.am (GNU_SYSTEM_MODULES): Add it.
* gnu/system/linux-initrd.scm (expression->initrd): Use (gnu build
linux-initrd) and 'write-cpio-archive' instead of the inlined code.
