bootstrap after crosshurd failing

[João <phlogiston@sapo.pt>]

Hello everyone,

Has anyone tried and succeeded installing hurd through crosshurd recently?

Upon the first boot, before native-install, I'm getting:

	Hurd server bootstrap: ext2fs[part:1:device:hd0] exec startupFailed to execute startup
	ext2fs: Executing '/hurd/startup': No such file or directory

I have managed to install the hurd on this computer via the CD image of the
2023 release, so I know that he hurd can run on this system.
I'm using the following grub entry, which worked with the system installed from
the CD iso:

	insmod part_msdos
	insmod ext2
	set root='hd-49,msdos1'
	if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root --hint-bios=hd-49,msdos1 --hint-efi=hd-49,msdos1 --hint-baremetal=ata-49,msdos1  00eba94a-9452-491a-ac60-70aa046e9972
	else
	  search --no-floppy --fs-uuid --set=root 00eba94a-9452-491a-ac60-70aa046e9972
	fi
	echo		'Loading GNU Mach ...'
	multiboot	/boot/gnumach-1.8-486-up.gz root=part:1:device:hd0 -s
	insmod part_msdos
	insmod ext2
	set root='hd-49,msdos1'
	if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root --hint-bios=hd-49,msdos1 --hint-efi=hd-49,msdos1 --hint-baremetal=ata-49,msdos1  00eba94a-9452-491a-ac60-70aa046e9972
	else
	  search --no-floppy --fs-uuid --set=root 00eba94a-9452-491a-ac60-70aa046e9972
	fi
	echo		'Loading the Hurd ...'
	module          /hurd/pci-arbiter.static pci-arbiter \
			--host-priv-port='${host-port}' --device-master-port='${device-port}' \
			--next-task='${acpi-task}' \
			'$(pci-task=task-create)' '$(task-resume)'
	module          /hurd/acpi.static acpi \
			--next-task='${disk-task}' \
			'$(acpi-task=task-create)' 
	module          /hurd/rumpdisk.static rumpdisk \
			--next-task='${fs-task}' \
			'$(disk-task=task-create)' 
	module		/hurd/ext2fs.static ext2fs --readonly \
			--multiboot-command-line='${kernel-command-line}' \
			--exec-server-task='${exec-task}' -T typed '${root}' \
			'$(fs-task=task-create)' 
	module		/hurd/exec.static exec '$(exec-task=task-create)'


The bootstrap process seems complicated
(https://darnassus.sceen.net/~hurd-web/hurd/bootstrap/), and I'm not sure how to
go about debugging this issue as the system does not boot.
Any suggestions?

Best regards,
João
