Update on bug#59196: `guix pull` fails on A20-OLinuXino-LIME2-eMMC

[Tanguy LE CARROUR]

Hi Guix,

After few… years (😵!?) I gave another try to Guix on A20-OLinuXino-LIME2.
Here is how it went…

I installed the latest Armbian (`25.2.0-trunk.72 bookworm`) on a new SD.
I updated the package list and then… `guix pull`!
83860 new commits and 7 hours later it successfully finished! 🎉
This is already better than last time!

Than, I tried to build the installation image:

```
$ guix system image --system=armhf-linux -e '((@ (gnu system install) os-with-u-boot) (@ (gnu system install) installation-os) "A20-OLinuXino-Lime2")'

😞

Plan B was to try to install Guix on the same drive following Julien’s blog post [1],
but I have no idea what a proper OLinuXino-Lime2 system config file
should look like!? For instance, what should the `bootloader` section be?! 🤔

Any help, idea or advice would be welcome!

Best regards,

Following Julien’s advice about cross compilation, I gave the installer
another try on a different computer having `qemu-binfmt-service`:

```
$ guix system image --system=armhf-linux -e '((@ (gnu system install) os-with-u-boot) (@ (gnu system install) installation-os) "A20-OLinuXino-Lime2")'

*ERF* 😞… so frustrating! 😱

Next attempt: install Guix System on top of the host distro’ and
offloading build to a remote server having `qemu-binfmt-service`!… 🤞
