Hi,
I am used to installing Debian by PXE and serial console. For that
purpose I'm familiar with editing the isolinux config files to have
the kernel serial settings (console=ttyS… etc) in isolinux/txt.cfg.
Now for the first time I am trying to install a system that has a
management controller that adds virtual media from ISOs, but I would
still like to see that install over the IPMI serial.
Currently when I add the Debian 12 netinst ISO as a virtual media it
EFI boots grub, not isolinux, so the output of grub only goes to the
graphical terminal (a web interface of the BMC in this case).
I can then force the install to proceed over serial by editing the
"Install" option and adding the familiar:
--- console=ttyS1,115200n8
pn the end of the kernel line, and that works, so I am nearly there.
I'd really like for this thing to boot grub in text mode on the
serial console though.
I guess I need to find the grub configuration that is in use from
the ISO and add the usual
serial --unit=1 --speed=115200 --word=8 --parity=no --stop=1
terminal_input serial
terminal_output serial
Should I just edit that into $iso_root/boot/grub/grub.cfg and repack
the ISO?
Is there any documentation page about this? Everything I found so
far just covers the isolinux bit, which doesn't appear to be
relevant here.
Thanks,
Andy
