Re: grub2, PXE boot, and freebsd 9.1

[Richard A. Sitze]

Hello Andrey,

per the docs [http://www.gnu.org/software/grub/manual/grub.html#Network]
I first tried:
* grub-mkimage --format=i386-pc-pxe --output=grub.pxe 
--prefix='(pxe)/grub' pxe pxecmd

Trial and error led me to make the following changes to that:
- removed pxecmd: module is not in 2.00, but was in older versions
- removed (pxe) from prefix

Your suggestion leads me to some side-questions:
1. Does grub-mkimage include transitive, or even simple, dependencies 
specified in moddep.lst for modules listed on it's command line?
2. If it doesn't, which modules *are* packaged by default?

Also, in moddep.lst, there are a number of dependencies shown for 
'pxe'.. including 'net', but not including 'tftp'.

Anyway, all that leads me to my current (possibly overkill) usage:
* grub-mkimage --format=i386-pc-pxe --output=grub.pxe --prefix='/grub' 
boot priority_queue datetime bufio net tftp pxe

and I do get further.  Thank you.

Alas, not all is well.  I now get "error:  timeout reading 
'/grub/i386-pc/normal.mod'".

Sigh.
