Hello, Thomas. Noce to hear from you.

LBA 0 is not an option. It will make hang, at least some versions OVMF,
quite possibly other firmwares as well. Nowadays what we have between 1
(inclusive) and isofs headers is all generated by xorriso (except on
sparc where we supply LBA 1)
It's possible to use another small value other than >1 in order to make
a set of headers at another position pointing to the same data.
Another workaround is to mount HFS+ filesystem which is already in a
partition (GPT one).
