Re: EFI amd64: boot.cfg goes where?

Thank you all for the patient help. It appears I am a bit more a fool
than I initially believed...

I mistakenly wrote disklabel instead of saying my root FFSv2ea
partition. My GPT drive does not have any disklabel partitions on it.
I'm new to GPT in general as I have only ever used MBR on
x86-compatibles, but I've been getting used to the Raspberry Pi boot
process and GPT is similar enough that I decided to dip my toes in.
disklabel is force of habit for me but I did read the guide very closely
while installing so thankfully I did not manage this.

In particular I'm glad you mentioned gpt(8) below because I had been
confused by my fdisk(8) outputs -- I've been sitting at one table and
talking to those at another!

Thank you very much, I was worried I had messed up my system somehow...

How could I find out?

Thank you all for your help, I'll have more time to test solutions
presented in these e-mails later today and will be re-reading all
mentioned man pages a bit more carefully.
