Ludovic Courtès f453f637d5 system: Allow the root file system to be named by UUID.
* gnu/build/file-systems.scm (canonicalize-device-spec)[canonical-title]:
Use 'string->uuid' to check whether SPEC is a UUID.
When SPEC is a string and CANONICAL-TITLE is 'uuid, call 'string->uuid'.
* gnu/system.scm (operating-system-grub.cfg): Add 'root-device'
variable and use it for the "--root=" argument.

variables.

Ludovic Courtès 78981bb9bd file-systems: Do not truncate mount points that already exist.
Reported by David Thompson <dthompson2@worcester.edu>
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.
2015-10-17 11:57:38 +02:00
David Thompson a72ccbc251 build: container: Fix call-with-clean-exit.

* gnu/build/linux-container.scm (call-with-clean-exit): Exit with status
  code of 0 if thunk does not throw an exception.
* tests/containers.scm: Add test.

Ludovic Courtès cc0e575a94 linux-boot: Mount /dev as a devtmpfs from the start.
Suggested by Petter <petter@mykolab.ch>
and Mark H Weaver <mhw@netris.org>.
Reported by Duncan Keall <duncan@duncankeall.com>.

Partly fixes <http://bugs.gnu.org/19190> by populating /dev/mapper
early enough.

* gnu/build/linux-boot.scm (mount-essential-file-systems): Mount /dev as
  a devtmpfs.
  (move-essential-file-systems): Add /dev.
  (mount-root-file-system): Mount /rw-root/dev as a devtmpfs instead of
  calling 'make-essential-device-nodes'.
  (boot-system): Remove call to 'make-essential-device-nodes'.
* gnu/system/file-systems.scm (%devtmpfs-file-system): Remove.
* doc/guix.texi (File Systems): Adjust accordingly.

Ludovic Courtès 0334ef2ab0 linux-initrd: Compress cpio archives deterministically.
* gnu/build/linux-initrd.scm (write-cpio-archive): Use '--no-name'.
2015-09-09 23:27:10 +02:00
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.

* 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.

2015-09-07 13:09:58 -04:00
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.
* tests/containers.scm ("container-excursion"): Update 'run-container' call.

  mounting a regular file.

  Rewrite to use 'initialize-partition' for each item of PARTITIONS.

  to #:modules default value.
  (qemu-image): Adjust accordingly.

David Thompson 5fd77f3f43 gnu: Make 'mount' interface in static Guile consistent with Guix API.
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.

Ludovic Courtès 6412e58a68 system: Don't make /boot/grub/grub.cfg a symlink to the store.
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.

  procedure is called from within 'call-with-error-handling' already.
2014-11-20 22:43:47 +01:00
Ludovic Courtès 1c27641f46 file-systems: Always write the options field in /etc/mtab.
* 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.
