Don't know about vfat, which is how I mount a floppy, but I just put 
that in the options list in /etc/fstab & will test it the next time I 
need to sneakernet something small around here.  Many thanks for what 
might be a valuable bit of info!

Well, you'll get one from me, but not because _I've_ blocked verizon (I've
done no such thing.)  Since I'm unable to verify verizon's addresses, all
mail from verizon is unable to be received here anymore.

(and yes, you get to read my reply via lkml...)

Thats the To: line of this message Russell, as it came in here.  I 
assume it was originally filled in to be to me and that you cleaned 
that to prevent your getting a bounce from verizon?

And no, it hasn't bounced yet as it typically will lay in the queue 
somewhere in lala land for anywhere from 4 hours to 6 or 7 days.  By 
that time the friggin message is no longer germain to the 
conversation, so they get deleted here.

Three step process
1 - get the RH source RPM and unpack
2 - get the kernel.org source of the same number
3 - use diff to generate the patch.

Optional step 4 - look at the size of it, shake your head and swear.

Indeed, and I now have a better solution which I don't even have to
think about anymore, and doesn't damage the headers in the message. 8)

Let me know if and when verizon comes back to reality please.

Now, this message did bounce, and the bounce message is damned 
confusing...

From: Mail Administrator <Postmaster <at> verizon.net>
 To: gene.heskett <at> verizon.net

This Message was undeliverable due to the following reason:

Your message was not delivered because the destination computer was
not found.  Carefully check that it was spelled correctly and try
sending it again if there were any mistakes.

It is also possible that a network problem caused this situation,
so if you are sure the address is correct you might want to try to
send it again.  If the problem continues, contact your friendly
system administrator.
