GTK+ 2 is still our default, so packages should generally not depend
on GTK+ 3. For instance, this causes Emacs to depend on both GTK+ 2
and 3, which is obviously a bad thing.
Issue #8990.
The resulting image can be copied to a SD card with `dd` and is directly
bootable by a suitably configured U-Boot. Though depending on the board, some
extra steps are required for copying U-Boot itself to the SD card.
Inside the image is a partition table, with a FAT32 /boot and a normal
writable EXT4 rootfs. It's possible to directly reuse the SD image's
partition layout and "install" NixOS on the same SD card by replacing
the default configuration.nix and nixos-rebuild, and actually is the
preferred way to use these images. To assist in this installation
method, the boot scripts on the image automatically resize the rootfs
partition to fit the SD card on the first boot.
The SD images come in two flavors; one for the ARMv6 Raspberry Pi,
and one multiplatform image for all the boards supported by the
mainline kernel's multi_v7_defconfig config target. At the moment, these
have been tested on:
- Raspberry Pi Model B (512MB model)
- NVIDIA Jetson TK1
- Linksprite pcDuino3 Nano
To build, run:
nix-build '<nixpkgs/nixos>' -A config.system.build.sdImage \
-I nixos-config='<nixpkgs/nixos/modules/installer/cd-dvd/sd-image-armv7l-multiplatform.nix>'
When using extlinux-conf-builder in a nix build using chroots, the
following error message could be seen:
/nix/store/XXX-extlinux-conf-builder.sh: line 121: cd: /nix/var/nix/profiles: No such file or directory
To avoid this, just skip the code path parsing /nix/var/nix/profiles
when $numGenerations (passed from the command line) is 0 (which is the
only legal value of $numGenerations in a nix build context).
Also use recurseIntoAttrs only on the default version (instead of only on 3.4).
The "self" variants (stil) don't build and they're inconsistent
versions. /cc @shlevy (fea2266290d6).
New features:
- Added eventloop and patch_stdout parameters to get_input.
- Inputhook support added.
- Added ShowLeadingWhiteSpaceProcessor and ShowTrailingWhiteSpaceProcessor
processors.
- Accept Filter as multiline parameter in 'shortcuts'.
- MultiColumnCompletionsMenu + display_completions_in_columns parameter
in shortcuts.
Backwards incompatible changes (not used in nixpkgs):
- Layout.width was renamed to preferred_width and now receives a
max_available_width parameter.
Fixes/features:
* Fix segfault in metrics because MMAPFORK macro not defined correctly
* Add --cpu-load-slice option for CPU stressor time slice tweaks
