Can't get ssh=password to work
Hi, I'm blind and I am trying to start grml64-full_2021.07.isoin a VirtualbBox virtual machine. I cannot seem to get the ssh daemon started. There doesn't seem to be much time to type in the "ssh=password" boot configuration parameter. What I do is to take a screen shot via the VirtualBox command. Then I run it through a optical char recognition program. This gives me a pretty good sense of what is on the screen. But no matter how fast I do it, I never seem to get a boot prompt.
I am thinking that maybe the process of typing in boot parms has changed since the switch to grub. onfiguration

Hm that's certainly annoying :(

Hm not really. But as you mention GRUB: when booting in old-style BIOS boot, the Grml ISO is using isolinux/syslinux as its boot loader. When booting with EFI enabled, bootloader GRUB is used. So maybe a different boot loader is being used than what you'd expect?
When running "VBoxManage showvminfo VM_NAME | grep Firmware" for your Grml VM, does it report BIOS or is it really EFI?
If it reports EFI, then GRUB will be used. Though the EFI boot entries could be wrong in your VM (due to a local disk where another operating system was installed to), then the ISO might not be considered for booting as first choice. Fixing this is sadly pretty annoying, even for non-blind users, as it requires pressing ESC during bootup at the very right moment, and then going into the boot manager menu.
What might be useful for you though is, enabling the ssh boot option by default. This can be done easily with grml2iso, which is provided by grml2usb (available from within plain Debian!).
The following command will give you a Grml ISO which automatically boots with boot option "ssh=grml", no matter what boot loader gets used then:
sudo grml2iso -b ssh=grml -o grml_ssh.iso grml64-full_2021.07.iso

Well, I established that i simply wasn't doing it fast enough. The virtual machine is booting via bios. I think my problem was partly due to it taking the screen reader some time to say the virtual machine had started, then taking the screen cap plus running it through the OCR program (even though i had scripted this) was taking so much time I was simply missing the boot prompt. So what I have to do is just start typing, trusting that it's there.
PS: Sorry for top-posting. With the screen reader, it's very difficult to do otherwise.
