This is what Bruce was talking about in another thread regarding using 
the kernel to boot from the EFI partition.  If I could use GRUB for 
this, I would change my grub.cfg file right now and test. But to try 

I didn't stop and delete anything I wrote because I wanted to show my 
train of thought.  I checked the 'gummiboot' man page.  Each boot option 
has a configuration file on the EFI partition.  I had forgotten that you 
can pass kernel boot options in that file. That's not possible using 
efibootmgr.  So maybe 'gummiboot' is the way to go.  It's easier and 
lighter weight than rEFInd and more versatile than efibootmgr.

I'm glad I thought of that.  I'm tired of configuring kernels.  Have 
done eight since Friday.  yuk.

You and Bruce are going to have to buy new hardware to check out all of 
this EFI stuff.  :)

I used dhclient a few years ago in my CLFS build and I had no problems.  
I forgot about that and went right to dhcpcd this time. In trying to 
learn about it, even the author says it's really finicky and harder to 
use.  It's just a configuration issue right now and I'll get it figured 
out--or get frustrated and go to dhclient.  :)

So that I don't have to advertise my "rustiness" with a subject line on 
the list, I've got a really noob question.  I can't dredge up the answer 
from the "grey cells."  What are the "key presses" to switch between 
terminals in a non-graphic environment?  I think ALT-CTRL-F[1-6] takes 
you to different run levels, but what about terminals?  Uhoh.  I think I 
just remembered something.  Am I thinking of ALT-CTRL-F[1-4]?
