Boot Fiwix and Linux without serial console on bare metal

[pder]

That seems to only change Fiwix kernel options. Or does it also propagate to Linux?

kexec_cmdline are the parameters passed to Linux.

kexec_cmdline=\"init=/init console=ttyS0\"

[pder]

Similar change to go_sysb would be good (so that console=ttyS0 is not used for sysc).

OK, so would this be for the case we are using the bare-metal option and providing a kernel?

No, just the different transition. You updated builder-hex0 to fiwix but there is Fiwix to Linux here: https://github.com/fosslinux/live-bootstrap/blob/master/sysa/run2.sh#L38

Oh indeed, we have a different path for bootstrapping. That other kexec only happens if we start with another linux kernel.

[fosslinux]

Huh, but where is the cmdline for sysc in kernel bootstrap mode? Does it exist?

Yes, see irc logs on #bootsrappable. On Fiwix future kexec cmdline has to be set in advance inside Fiwix cmdline (kexec_cmdline parameter)

https://github.com/mikaku/Fiwix/issues/29 documents this a bit.

I updated go_sysb to adjust kexec parameters based on if bare metal option is chosen.

I verified that ./rootfs.py -q -qk mykernel still works.

I am not sure how to test this set of options: ./rootfs.py -b -qk mykernel -p

The instructions provided are: Please:

1. Take tmp/sysa/initramfs and your kernel, boot using this.
2. Take tmp/sysc/disk.img and put this on a writable storage medium.

Any ideas on how to test this?

[fosslinux]

You would use GRUB or something similar and then linux path/to/kernel and initrd path/to/initramfs.

[stikonas]

Hmm, it's probably fine to just test this in qemu... We never really tested GRUB before anyway. Though if you can, that would be an interesting test.

[fosslinux]

I have once before, but it's been a fair while since I've tested it..
