Hi,

I'm running a flash-based system w/ grub2. I do not want grub2 writing to my
boot partition? How can I prevent the grubenv file from being written in any
(and all) cases?

Thank you.

Just remove grubenv file. But I doubt a single (at most) write per boot
would wear your flash in its lifetime even if you reboot every 10 minutes

Allas, the data being written is "recordfail", which causes problems on a
headless system.

recordfail main use is exactly the headless system. Just default ubuntu
on boot failure shows the menu but on headless you should make it point
to surely working kernel. Have a look at  /etc/grub.d/00_header

Thanks, I looked at it. But making the change you suggest is not clear. I
only see where timeout is set to -1. How do you specify a boot target in
this case? Anyway, I think i'm set with the first suggestion.
