Tested the master branch or your kexec-tools, I got below with
"mount -o bind /root /proc" because there's some other issues for my customized
kernel to boot:
arch_process_options:95: initrd: (null)
arch_process_options:96: dtb: apm-mustang.dtb
arch_process_options:97: lite: 1
arch_process_options:99: port: 0x0
kernel: 0x3ff9cbb0010 kernel_size: 0x602c947
unrecoverable error: could not scan "/proc/device-tree/": No such file or directory
