file-systems: Handle EIO error in 'ENOENT-safe' as well.
Trying to boot GuixSD when an audio CD is in the drive will die with an
"input/output error" when trying to read the superblock from the cd
drive.

This patch catches and warns in this case rather than dying.

* gnu/build/file-systems.scm (ENOENT-safe): Handle EIO.

vm: Add missing module.
* gnu/build/vm.scm (define-module): Use module (guix build syscalls).

It fixes the following warnings during guix build :

gnu/build/vm.scm:233:3: warning: possibly unbound variable `mount'
gnu/build/vm.scm:238:3: warning: possibly unbound variable `umount'
gnu/build/vm.scm:268:8: warning: possibly unbound variable `mount'

gnu/build/vm.scm:315:4: warning: possibly unbound variable `mount'
gnu/build/vm.scm:323:4: warning: possibly unbound variable `umount'

This was not possible until the previous commit because we had to be sure
that Guile core implementation of 'mount' and 'umount' was used in
initrd context.

file-systems: 'disk-partitions' detected partitions from mapped devices.
Previously, partitions of mdadm- or cryptsetup-produced block devices
would not be returned by 'disk-partitions'.

* gnu/build/file-systems.scm (disk-partitions)[last-character]: New
procedure.

container: Allow 'container-excursion' to the same namespaces.
Before that, 'container-excursion' would call 'setns' even when the
target namespace is the one the caller is already in, which would fail.

* gnu/build/linux-container.scm (container-excursion): Introduce
'source' and 'target'.  Compare the result of 'readlink' on these
instead of comparing file descriptors to decide whether to call
'setns'.
* tests/containers.scm ("container-excursion, same namespace"): New test.

at <https://lists.gnu.org/archive/html/guix-devel/2015-10/msg00284.html>.

* gnu/build/file-systems.scm (mount-file-system): When SOURCE matches
  'regular-file?', do not create MOUNT-POINT if it already exists.  This
  fixes a bug whereby we would be truncating MOUNT-POINT if it already
  existed.

David Thompson ee78d02452 build: container: Use the same clone flags as fork(3).
The intent is to make 'clone' behave a lot more like 'primitive-fork', which
calls clone(2) with SIGCHLD, CLONE_CHILD_CLEARTID, and CLONE_CHILD_SETTID
flags.  Notably, running 'clone' at the REPL without these flags would break
the REPL beyond repair.

  variables.
* gnu/build/linux-container.scm (namespaces->bit-mask): Add

David Thompson 831bc1468e 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.
