I'm not where I can look it up, but ISTR Linux starts with the 'zeroth' 
partition - GPT or otherwise.

Your previous post w/r 'reserved' compatibility slice 0 explains (finally) why 
FreeBSD has always appeared to 'start' with 1. Seems there is/was a method to 
their apparant inconsistency after all?

'Spose I'd have known that if I ran anything that neeed a 'compatibility' slice.

W/R going GPT-way or legacy FreeBSD way - perhaps use of zeroth should be 
weighed vis whatever FreeBSD 7.X is doing?

I mean - with whom/what/(anything?) should DFLY try for compatibility?

HTH,
