2015-09-20linux-boot: Mount /dev as a devtmpfs from the start.Ludovic Courtès
Suggested by Petter <petter@mykolab.ch> and Mark H Weaver <mhw@netris.org>. Reported by Duncan Keall <duncan@duncankeall.com>.

* gnu/build/linux-initrd.scm (write-cpio-archive): Use '--no-name'.
2015-09-07build: container: Use the same clone flags as fork(3).David Thompson
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. * guix/build/syscalls.scm (CLONE_CHILD_CLEARTID, CLONE_CHILD_SETTID): New variables. * gnu/build/linux-container.scm (namespaces->bit-mask): Add CLONE_CHILD_CLEARTID and CLONE_CHILD_SETTID to bit mask.

2015-08-08build: container: Add #:host-uids argument to call-with-container.David Thompson
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.

Add #:partitions. Rewrite to use 'initialize-partition' for each item of PARTITIONS. * gnu/system/vm.scm (expression->derivation-in-linux-vm): Add (guix records) to #:modules default value. (qemu-image): Adjust accordingly.
2015-07-24vm: Use the 'umount' procedure instead of util-linux's 'umount' command.Ludovic Courtès

(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.

2015-06-19gnu: Make 'mount' interface in static Guile consistent with Guix API.David Thompson
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.
