* doc/guix.texi (Invoking guix graph): Document it.
import: gem: Fix minor bug and add unit test.

licenses. When rendering a list of licenses, cons 'list onto the front of
the expression.

Fixes <http://bugs.gnu.org/21280>.
Reported by Leo Famulari <leo@famulari.name>.
* tests/nar.scm (file-tree-equal?): Use #t as the initial result. Btrfs would
set nlink to 1 instead of 2 for an empty directory, thereby leading
'file-tree-equal?' to return #f.

space", "formatting: long line", "formatting: alright"): New tests.
* doc/guix.texi (Invoking guix lint): Mention the 'formatting' checker.
tests: containers: Skip if setgroups file does not exist.
Fixes bug #21226.
Linux 3.19 introduced a fix for a security vulnerability in user namespaces.
This fix introduced a new proc file called 'setgroups' and was backported to
many older kernels. However, some users run a kernel that is new enough to
support user namespaces yet old enough to not include the patch, so we must
skip the tests.
* tests/containers.scm: Skip all tests if /proc/self/setgroups does not exist.
build: container: Add #:host-uids argument to call-with-container.
It's not always possible to map 65536 uids when creating a container as the
root user within another user namespace. This is true when building Guix
within the build daemon's container. By using a uid range of 1 by default,
even as the root user, the tests now pass.
* gnu/build/linux-container.scm (initialize-user-namespace, run-container):
Add 'host-uids' argument.
(call-with-container): Add #:host-uids keyword argument.
* tests/containers.scm ("container-excursion"): Update 'run-container' call.
syscalls: Add 'network-interfaces', which wraps libc's 'getifaddrs'.
Based on discussions with Rohan Prinja <rohan.prinja@gmail.com>.
* guix/build/syscalls.scm (<interface>): New record type.
(write-interface, values->interface, unfold-interface-list,
network-interfaces, free-ifaddrs): New procedures.
(ifaddrs): New C struct.
(%struct-ifaddrs-type, %sizeof-ifaddrs): New macros.
* tests/syscalls.scm ("network-interfaces returns one or more interfaces",
"network-interfaces returns \"lo\""): New tests.
syscalls: Rename 'network-interfaces' and 'all-network-interfaces'.
* guix/build/syscalls.scm (network-interfaces): Rename to...
(network-interface-names): ... this.
(all-network-interfaces): Rename to...
(all-network-interface-names): ... this.
* gnu/services/networking.scm (dhcp-client-service): Adjust accordingly.
* tests/syscalls.scm ("all-network-interfaces"): Rename to...
("all-network-interface-names"): ... this, and adjust accordingly.
("network-interfaces"): Rename to...
("network-interface-names"): ... this, and adjust accordingly.
tests: Skip container tests if namespaces are not available.
* tests/containers.scm: Skip all tests if user namespaces do not exist.
tests: Make #:references-graphs gexp test more tolerant.
* tests/gexp.scm ("gexp->derivation #:references-graphs"): Use 'lset=' instead
of 'equal?' since the order in which references are listed in not
guaranteed.
