system: hurd-boot: Prepare for runsystem in Guile.

2026-05-19T16:34:56+00:00

Fo guile to run, it needs pipe support: without pipe support it aborts at
startup.  Pipe support is currently createn in runsystem by creating a
passive translator

    settrans --create /servers/socket/1 /hurd/pflocal

However, this needs a writable root file-system, and runsystem is started with
a readonly root file-system.

This patch enables running guile early in runsystem, and thus prepares for
replacing the runsystem shell script with a guile program, by embedding the
servers/socket/1 passive translator into the hurd system image using xattr.

* gnu/build/hurd-boot.scm (make-hurd-device-nodes): Change optional root
parameter to keyword #:root.  Add #:hurd keyword parameter.  Use it to
create servers/socket/1 (pipe) and proc passive xattr translators.
* gnu/build/image.scm (initialize-root-partition): Update caller.
* gnu/system/image.scm (with-imported-modules*): Include (ice-9 optargs).
* gnu/system/images/hurd.scm (hurd-initialize-root-partition): Use it to
update caller.
* guix/scripts/system.scm (install): Update caller.

describe: Define and use ‘modules-from-current-profile’.

2026-01-25T20:17:44+00:00

Fixes .

Fixes a bug whereby bootloader, image, platform, etc. modules would be
searched for in locations other than the current profile, possibly leading to
incompatible files being loaded.  More generally, this bug would break
statelessness: depending on what happens to be available in $GUILE_LOAD_PATH,
some modules would or would not be loaded.

* guix/describe.scm (modules-from-current-profile): New procedure.
* gnu/bootloader.scm (bootloader-modules): Use it instead of ‘all-modules’.
* gnu/system/image.scm (image-modules): Likewise.
(not-config?): Rename to…
(neither-config-nor-git?): … this, and add (guix git).  Adjust users.
* guix/import/utils.scm (build-system-modules): Likewise.
* guix/platform.scm (platform-modules): Likewise.

image: Use `unshare` to map root user for btrfs

2026-01-12T09:56:38+00:00

The current version of `mkfs.btrfs` has a regression when combined with
`fakeroot` where it does not detect the faked root uid/gid of files when
building the filesystem. This produces partition images with `/` owned by
the guixbuild user when it should be owned by root.

Using `unshare` rather than `fakeroot` resolves this by doing the uid
mapping at the kernel level rather than overloading the `stat` function.

An equivalent issue was [reported and patched in
NixOS](https://github.com/NixOS/nixpkgs/pull/434122)

* gnu/build/image.scm (system-disk-image): Import `util-linux` instead of
`fakeroot`.
* gnu/system/image.scm (make-btrfs-image): Use `unshare --map-root-user`

image: operating-system-for-image: Bring back root-fs placeholder.

2025-12-26T18:54:23+00:00

To calculate the UUID in `root-uuid`, the operating-system has to have a root
file system, because it's typically used in the
operating-system-boot-parameters.

Followup of efc32c6684f75531cfd600874ba5d23a0bd643b9 that it partially reverts.

* gnu/system/image.scm (operating-system-for-image): Re-introduce root file
system to operating-system used to calculate the UUID.

image: Add /boot/efi filesystem if operating-system specifies it.

2025-12-22T22:00:39+00:00

Instead of forgetting about the /boot/efi system completely, re-add it
with proper label. This way lightweight.tmpl, desktop.tmpl still
boot when supplied to guix system image. That was the reason for
removing /boot/efi file-system in the first place. Removing it however
means the target system cannot be reconfigured by default, as the
esp is not mounted.

* gnu/system/image.scm
(partition-has-flag?): New variable.
(root-partition?): Use it.
(find-partition-with-flag): New variable.
(find-root-partition): Use it.

label instead of removing it completely.

image: Add qcow2-gpt image type.

2025-12-22T22:00:38+00:00

qcow2 is a mbr-hybrid image. But on aarch64, we
have to use grub-efi bootloader. For that bootloader,
gpt should be used and Guix errors if it isn't (due to
failed check in Guix code). So it's impossible to generate
qcow2 type aarch64 image without using customized bootloader.
One would have to define their own image instead of using
the ones pre-defined.

* gnu/system/system.scm (qcow2-gpt-image-type): New variable.
* doc/guix.texi: Document qcow2-gpt and its use.

2025-12-22T22:00:37+00:00

Let the user decide for grub/grub-efi in cases where
grub-hybrid is unsupported. This is the case on
aarch64, where grub-pc is not supported, so only
grub-efi can be used.

* gnu/system/image.scm (operating-system-for-image):
Do not replace bootloader with grub-mkrescue-bootloader
for iso9660 when grub-hybrid is not supported.

image: esp32-partition/grub: Pass root to initialize-efi32-partition.

2025-12-13T13:26:52+00:00

Follow up of: ca0ed91b40 where the root argument has been omitted.
This leads to an error, because initialize-efi32-partition expects
`root` as first argument, while `#:grub-efi32` was given.
Fixes: #4634.

* gnu/system/image.scm (esp32-partition/grub): Pass 'root' as first argument
to initialize-efi32-partition.
