grub2pxe give a specific cfg file per host

grub2pxe give a specific cfg file per host

[Yoann Moulin]

Hi,

I'm testing grub2pxe and I'd like to know if it's possible to give
different configfile (diff that grub.cfg) per host/mac address such as
pxelinux does with mac address detection.
option-150 was used for that before but seem to not be implemented with
grub2

I'd like to do something like into the dhcpd.conf file:

host test1 {
 hardware ethernet 00:1c:42:01:f8:18;
 fixed-address test1.local;
 filename "grub2pxe";
 option option-150 "/boot/grub/test1.cfg";
}

where /boot/grub/test1.cfg might be a symlink on a default file.cfg or a
specific file.

is that something already implemented ? if not is there any plan for
something like that ?

Test environment :
- Parallels for Mac 4
- boot server runs Centos 5.3
- grep2pxe build from grub-1.97~beta4
- kernel : 2.6.18-164.el5

thanks for your help

   This is something that's absolutely essential to our customers.  It's 
something we rely on in Legacy GRUB and it's something that we'll need in 
GRUB2 when we make the transition.

good :)

but is that mean it's not possible yet to do something like that right now ?

Hi,

Yeah, it's impossible to do it now. But this feature is not difficult
to add using the tree config loader from my menu branch, I'd post a
patch soon.
