[PATCH 00/16] Installer support for (cross) installing the Hurd. |
|
Date: |

Hi!
This patch set adds initial support for installing and running the Hurd on
real iron. Writing a draft blog post on all the Hurd work that we've done
last year and describing the clumsy way to install a Hurd system inspired me
to have another look at the installer.
I've dusted off some old patches to fix booting a Hurd installation more than
once, then there's some preliminary (installer) work and then it adds a
"Kernel" selection page where you can optionally select "Hurd" next to the
default "Linux Libre".
If you select "Hurd", some defaults are changed such as using an ext2 file
system, some options are disabled such as creating an encrypted partition or a
swap partition, and some menus have a warning about availability of packages.
Finally a fully functional "config.scm" is created for installing the Hurd.
It is using the regular GNU/Linux installer for now and the Hurd system is
being cross installed. It might be nice to have a Hurd based installer image
some time, maybe when we have better networking support (rumpnet? ;).
I've updated the `hurd-team' branch with this patch set. To build the
installer, do something like
--8<---------------cut here---------------start------------->8---
./pre-inst-env guix system image -t iso9660 gnu/system/install.scm
or
./pre-inst-env guix system image -t iso9660 --system=i686-linux
gnu/system/install.scm
--8<---------------cut here---------------end--------------->8---
(note that the 32bit version using linux-libre-6.10.13 panics for me, I've had
success with linux-libre-5.15 (see
<https://git.savannah.gnu.org/cgit/guix.git/commit/?id=80f8ef0a01f2cf39deebfecc344e5f04d87d4bd4>).
The last, but not unimportant feature, are patches to run the installer in
dry-run mode and especially to run it directly from Guile, i.e., without
building the (current-guix) guix derivation for the `hurd-team' branch and
whatnot.
To run the installer (semi-) directly, do something like:
--8<---------------cut here---------------start------------->8---
/pre-inst-env guile -c '((@ (gnu installer) run-installer) #:dry-run? #t)'
or
sudo -E ./pre-inst-env guile -c '((@ (gnu installer) run-installer))'
--8<---------------cut here---------------end--------------->8---
BE VERY CAREFUL WHEN NOT USING #:DRY-RUN #T!
It feels a bit clumsy because it still builds a lightweight installer script
in the store. We could avoid going via the store and factor-out the gexp'ed
installer steps list from the `installer-steps' procedure. This is
problematic because it then needs (newt), (parted), and (webutils) modules to
build the installer OS. We could just add guile-newt, guile-parted,
guile-webutils to the guix package's dependencies but I figured, also from how
the installer was written, that we really don't want this.
I also tried using #:autoload (see
<https://git.savannah.gnu.org/cgit/guix.git/commit/?id=841b0f00afcc57442e348cdec7ca4fcae8372afb>),
but #:autoload seems to fail on record predicates like `disk?'
--8<---------------cut here---------------start------------->8---
Wrong type to apply (#<syntax-transformer disk?>).
--8<---------------cut here---------------end--------------->8---
and also tried adding an extra indirection
(see
<https://git.savannah.gnu.org/cgit/guix.git/commit/?id=29a65fa3d251fe1cffea6db5231a0eb7c339987b>)
in the hope to avoid having to use #:autoload for (parted), but as yet to no
avail.

Yes, I still think this is a nice idea. Better to open a new bug for
that when someone wants to write a patch?
Pushed to master as 035e5f0c743d80be3d4029f9daba90cb8b657782.
Thanks!
