Error in install-efi + build with graft freezes

Error in install-efi + build with graft freezes

[phodina]

Hi Guix,

I've attempted to build image for beaglebone black based on the example found in gnu/system/examples/beaglebone-black.tmpl. To build the image I run the following command:

time guix system image --no-grafts --system=armhf-linux examples/beaglebone-black.tmpl -v3
The following derivations will be built:
   /gnu/store/1ivscl4dkmw65lgl3s7ml8qgx8dgj6zv-disk-image.drv

Based on the backtrace the issue is in install-efi-loader calling install-efi with incorrect parameter. I checked also the gnu/build/bootloader.scm where these function are defined.

Unfortunately, I'm not that skilled in Guile to debug the code, set breakpoint and view/modify the arguments.

Could you recommend me some guide how to debug the Guile code in order to learn how to fix this issue?

Also one more question related to the Guix. I had to use the argument --no-graft. When I measure the time it takes to build the system with grafts the process freezes for like a half day so I kill it. Without the grafts I at least get to the partition error above.

Could someone please explain the reason or point me in the right direction why grafts freeze or is it normal it takes that long?
(for cross-compilation, when building native system for my laptop I don't see this issue)
