i thoufgt th accepted way was, (assumping your machine has an IDE interface),
to use an IDE to compact flash adapter and and a CF card, and store the
nvram on this.
this gives you the simple interface of IDE but no rotating disks.

That's a much more expensive and involved
method than tacking on a little USB key, to
which you've copied nvram data using `dd'.
ron's method above, with a simple
`dd -if nvram -of /dev/sdU0.0/data' and
three lines in plan9.ini did the trick.
No rotating disks.
The other problem is that my box

You can get small IDE DOMs for under ten bucks. No need for CF adapters.
rusty power supply that seems incapable
of handling any IDE devices. Not sure
what's going on at this point, really. But
it does fine as a basic CPU server (more
of an interface to Plan 9 from other OS's).
do yourself a favor. don't run with a dodgy power supply.
there are just too many
I just took all the disks out of my cpu server.
I'm booting from my fileserver. I get the following
prompts (which make the bootup process really
non-automated):

can't open nil: unknown device in # filename
authid: bootes
authdom: mydom
secstore:
password:

Some time ago I modified the rtc driver so we could use '#r/nvram'
(oh, gosh, this was almost 10 years ago but ...) so that we could use
the CMOS to store this stuff. Maybe it's time for another look.

vorsicht! there's a lot of magic
Well, I don't have a dedicated AoE for secure keys.
Alternatively, can I store the keys on a little USB
device? Does it require anything more than a change
to the INI (in this case PXE) file?

Sure. but it's been done. We did it.

yeah, the usb would be a great place to store it! Then you can easily
rewrite the key ...

Sure, but how do mounting and reading and all
that jazz, work on boot?

write to the raw disk, and use the device name for nvram in plan9.ini

it's probablly worth mentioning that if you have nvram
in an emulator, your secstore password is available in the
clear to whomever can read your emulator's emulated disk.

no. it happens to me all the time. (when there is no

OK, but you won't hit an error in that case either. I was wondering
whether the i/o problem was tripping it up.

factotum handles this case.

no it doesn't, I had this a few days ago, moving disks about so
nvram couldn't be found. I could still boot the system but I had to enter
the nvram info from the keyboard, it did then try to write the data back
which (of course) fails - perhaps it was this write to a dead disk that
caused the boot

Okay, it's authsrv(2) that describes the nvram search sequence. And for

grab the nvram across the wire, which in hindsight makes no sense

i guess i need to update this man page. i didn't recall the
search algorithm was documented. thanks for pointing that out.
sorry for the obtuse reference. now that i've made it on the list,
i'll just explain myself. i made a local change to how

no more disk. We used this when Andrey
put plan 9 in FLASH.
It was nice to not have any spinning media for nvram.
It gets a little tricky because cmos is not sane in where you can
store bits, but it's doable.
