[RESEND] [PATCH] nfsroot.txt (against Linux 2.6.15.2)

Hello dear developers,

I today booted the first time my embedded device using Linux 2.6.15.2,
which was booted by pxelinux, which then bootet itself from the nfsroot.

This went pretty fine, but when I was reading through
Documentation/nfsroot.txt I saw that there are some more modern versions
available of loading the kernel and passing parameters.

So I added them and the patch for that is attached to this mail.

Sincerly,

Nico

P.S.: Please reply to nico-kernel2 //at// schottelius.org

Looks good.

Inline patches preferred.

Easier if this is your From: address, initially ;-)

Patches must be in a format that applies with `diff -p1'. diffstat(1)
output doesn't hurt, either. See Documentation/SubmittingPatches and
http://www.zip.com.au/~akpm/linux/patches/stuff/tpp.txt for details.

Right. Silly me.

[RERESEND] [PATCH] Updated Documentation/nfsroot.txt

[Nico Schottelius]

[-- Attachment #1: Type: text/plain, Size: 2926 bytes --]

[I followed the instructions in
 http://www.zip.com.au/~akpm/linux/patches/stuff/tpp.txt and
 Documentation/SubmittingPatches and corrected my patch submission.
 I hope it's ok this time. I copied the original text so you can
 use it for the changelog.]
