Also, is kdump crashkernel supported in GuixSD?
The minimal support would be:
pass kernel command line option "crashkernel", for example crashkernel=256M.
This reserves a region of memory not to be touched by anyone but the crash
analyzer (especially not by DMA).
Better support would be (see linux/Documentation/kdump/ ):
Enable CONFIG_DEBUG_INFO in the kernel config. The remaining are all already
active in GuixSD.
For x86_64, after booting, run
kexec -p kernelimagefile --initrd=... --append="root=... 1 irqpoll
maxcpus=1 reset_devices"
