Simon Glass has proposed merging ~sjg1/curtin:boot2 into curtin:master.
Commit message:
Curtin currently assumes that grub is used as the bootloader.
Generalise the schema to support multiple bootloaders
TBD: Add extlinux support
DO NOT SQUASH
Requested reviews:
curtin developers (curtin-dev)
For more details, see:
https://code.launchpad.net/~sjg1/curtin/+git/curtin/+merge/480712
The idea here is to allow MAAS to set up RISC-V clients without needing grub.
They can use extlinux instead, meaning that U-Boot is enough to handle the full
boot.
I have made the schema changes but I need to figure out how to get the device
and mount point for the root and boot devices.
--
Your team curtin developers is requested to review the proposed merge of
~sjg1/curtin:boot2 into curtin:master.

-curthooks
-~~~~~~~~~
-Configure how Curtin determines what :ref:`curthooks` to run during the installation
-process.
-
-**mode**: *<['auto', 'builtin', 'target']>*
-
-The default mode is ``auto``.
-
-In ``auto`` mode, curtin will execute curthooks within the image if present.
-For images without curthooks inside, curtin will execute its built-in hooks.
-
-Currently the built-in curthooks support the following OS families:
-
-- Ubuntu
-- Centos
-
-When specifying ``builtin``, curtin will only run the curthooks present in
-Curtin ignoring any curthooks that may be present in the target operating
-system.
-
-When specifying ``target``, curtin will attempt run the curthooks in the target
-operating system. If the target does NOT contain any curthooks, then the
-built-in curthooks will be run instead.
-
-Any errors during execution of curthooks (built-in or target) will fail the
-installation.
-
-**Example**::
+boot
+~~~~
- # ignore any target curthooks
- curthooks:
- mode: builtin
+Configures which bootloader(s) Curtin installs and some associated options.
+This is a list, which can contain up to two options: `grub` and `extlinux`.
- # Only run target curthooks, fall back to built-in
- curthooks:
- mode: target
+Two bootloaders are available:
+- `GRUB <https://www.gnu.org/software/grub/>`_ (GRand Unified Bootloader)
+ installs itself on one or more block devices and takes care of booting.
+ Typically grub is built as an EFI application. Curtin controls aspects of
+ grub's configuration-file (/boot/grub/grub.cfg) which tells grub which OS
+ options to present to the user.
-debconf_selections
-~~~~~~~~~~~~~~~~~~
-Curtin will update the target with debconf set-selection values. Users will
-need to be familiar with the package debconf options. Users can probe a
-packages' debconf settings by using ``debconf-get-selections``.
+- `extlinux <https://wiki.syslinux.org/wiki/index.php?title=EXTLINUX>`_
+ is really just a file format, similar to a grub configuration-file but much
+ less flexible. It specifies which OS options to present to the user.
-**selection_name**: *<debconf-set-selections input>*
+One or both can be installed.
-``debconf-set-selections`` is in the form::
+The following properties are used for both bootloaders:
- <packagename> <packagename/option-name> <type> <value>
+**bootloaders**: *<list of bootloaders>*
-**Example**::
+Selects the bootloaders to use. Valid options are "grub" and "extlinux".
- debconf_selections:
- set1: |
- cloud-init cloud-init/datasources multiselect MAAS
- lxd lxd/bridge-name string lxdbr0
- set2: lxd lxd/setup-bridge boolean true
+**replace_linux_default**: *<boolean: default True>*
+Controls whether grub-install will update the Linux Default target
+value during installation.
+**terminal**: *<['unmodified', 'console', ...]>*
-disable_overlayroot
-~~~~~~~~~~~~~~~~~~~
-Curtin disables overlayroot in the target by default.
+For grub, this configures the target-system grub-option GRUB_TERMINAL
+``terminal`` value which is written to
+/etc/default/grub.d/50-curtin-settings.cfg. Curtin does not attempt to validate
+this string, grub2 has many values that it accepts and the list is platform
+dependent.
-**disable_overlayroot**: *<boolean: default True>*
+For extlinux, this puts the console string in an APPEND line for each OS.
-**Example**::
+If ``terminal`` is not provided, Curtin will set the value to 'console'. If the
+``terminal`` value is 'unmodified' then Curtin will not set any value at all and
+will use Grub defaults.

+Curtin can add an ``extlinux.conf`` file to a filesystem. This contains a list
+of possible kernels, etc. similar to grub. This is somewhat more flexible on
+ARM/RISC-V since it can use `FIT <https://fitspec.osfw.foundation/>`_ and deal
+with devicetree, verified boot, etc. automatically. It also avoids specifying
+which bootloader must be used, since extlinux is supported by U-Boot, for
+example.

+curthooks
+~~~~~~~~~
+Configure how Curtin determines what :ref:`curthooks` to run during the installation
+process.
+
+**mode**: *<['auto', 'builtin', 'target']>*
+
+The default mode is ``auto``.
+
+In ``auto`` mode, curtin will execute curthooks within the image if present.
+For images without curthooks inside, curtin will execute its built-in hooks.
+
+Currently the built-in curthooks support the following OS families:
+
+- Ubuntu
+- Centos
+
+When specifying ``builtin``, curtin will only run the curthooks present in
+Curtin ignoring any curthooks that may be present in the target operating
+system.
+
+When specifying ``target``, curtin will attempt run the curthooks in the target
+operating system. If the target does NOT contain any curthooks, then the
+built-in curthooks will be run instead.
+
+Any errors during execution of curthooks (built-in or target) will fail the
+installation.
+
+**Example**::
+
+ # ignore any target curthooks
+ curthooks:
+ mode: builtin
+
+ # Only run target curthooks, fall back to built-in
+ curthooks:
+ mode: target
+
+
+debconf_selections
+~~~~~~~~~~~~~~~~~~
+Curtin will update the target with debconf set-selection values. Users will
+need to be familiar with the package debconf options. Users can probe a
+packages' debconf settings by using ``debconf-get-selections``.
+
+**selection_name**: *<debconf-set-selections input>*
+
+``debconf-set-selections`` is in the form::
+
+ <packagename> <packagename/option-name> <type> <value>
+
+**Example**::
+
+ debconf_selections:
+ set1: |
+ cloud-init cloud-init/datasources multiselect MAAS
+ lxd lxd/bridge-name string lxdbr0
+ set2: lxd lxd/setup-bridge boolean true
+
+
+
+disable_overlayroot
+~~~~~~~~~~~~~~~~~~~
+Curtin disables overlayroot in the target by default.
+
+**disable_overlayroot**: *<boolean: default True>*
+
+**Example**::
+
+ disable_overlayroot: False
+
+grub
+~~~~
+
+This is an alias for **boot** with *bootloader* set to "grub". It is provided
+to maintain backwards compatibility
