[gentoo-user] grub + pxeboot

[Enrico Weigelt]

Hi folks,


I'd like to let grub boot an PXE bootloader, so I've got the 
option to boot from network instead of local disk.
How can I do this ?

Currently I'm using an PXE bootdisk to boot from network, but 
this is not satisfying.


thx

There was a really good guide on how to do this (at least, from the point of
view of booting an nfs-mounted root directory) in the alternate installation
guide.  I'm pretty sure that you have to compile grub with the
--enable-diskless option.  I'm not really sure how to do that easily within
portage, but I'm sure someone will chime in with an appropiate answer.
Obviously PXE-booting requires a machine with a modern enough BIOS to
support it.

The "netboot" use flag seems to be the right thing ;) it seems that it
enables other things beside "--enable-diskless" that look like network
drivers/whatever.. (never tried it)

BTW if you want to pass something to ./configure in an  emerge, just use

EXTRA_ECONF="--enable-diskless" emerge -av grub

But I don't know if it can be set pernamently for that package in some
file in /etc/portage/....

Awesome tidbit, I'll be sure to file that one away.  Also, if you're
configuring for a netboot, the definitive place to look is in the
kernel tree itself.  I would especially recommend
Documentation/initrd.txt, which is great for netbooting something
that's not going to be a diskless thinclient.  Regardless, that should
tell you everything you need to know, or where to look for the few
pieces you're missing.
