Hi all,
I just released the first barebox for 2026! v2026.01.0 is out.
This brings us some exciting new features. First to mention is that barebox
no longer can only be a EFI payload, but also act as an EFI loader. With this
barebox can now boot Debian images out of the box. A lot of work has been done
to get this 54 patches series and even more preparatory patch series into
barebox,
thanks Ahmad for not giving up on this.
Another change is that barebox now has device special files in /dev/ rather than
regular files that have a cdev beneath them. With this we no longer have a devfs
filesystem anymore and /dev/ simply becomes a regular directory in the initial
ramfs mount. Links are no longer special and we'll be able to create
/dev/disk/by-*/
entries.
barebox now also has "storage.removable" and "storage.builtin" boot aliases to
allow booting from the specified device class.
Finally the family of supported boards gets a new member: The Amazon Kindle
generation 6/7 are now support.
See below for migration guide and patches that went into this release.
Have Fun!
Migration guide for Release v2026.01.0
======================================
<config.h> removal for PowerPC
------------------------------
PowerPC was the last remaining user of per-board ``<config.h>`` files.
The alternative for out-of-tree boards is now to patch
``arch/powerpc/include/asm/config.h`` to include the board's config.h,
like the in-tree boards are already doing.
Filesystems
-----------
``{linux.bootargs}`` is replaced with ``root={linux.bootargs.root}
{linux.bootargs.rootopts}``
The variable linux.bootargs has been replaced by the two variables
linux.bootargs.root and linux.bootargs.rootopts, splitting the previous bootargs
into three parts. A nonexistent fixed "root=", then the root filesystem and then
additional optional params for this particular filesystem.
for example the previous::
linux.bootargs="root=/dev/nfs nfsroot=192.168.1.1:/rootfs"
becomes::
linux.bootargs.root="/dev/nfs"
linux.bootargs.rootopts="nfsroot=192.168.1.1:/rootfs"
Boards
------
ARM i.MX6 RIoTboard
^^^^^^^^^^^^^^^^^^^
The barebox update handler has been changed to write barebox to the
eMMC boot partitions rather than the user data area.
CONFIG_SHELL_NONE
-----------------
If there's nothing to do for a shell-less barebox, it will now attempt
to poweroff the system instead of busy-looping indefinitely.
This changes behavior for systems that rely on a watchdog to reset
a hanging barebox in this situation. If this breaks anything for you,
please reach out.
