One of the main difficulties is that A/UX and MacOS have different views about 
which fields in an official partition map entry are actually significant. Back 
during the A/UX 2.0 beta period, I formatted & partitioned a drive using the 
supplied non-Apple software, and it worked fine under MacOS. Looked at from 
A/UX, the partition map entry magic numbers were all zero (not the correct 
value!). 

I asked Apple DTS to issue a technote on this area, and was told "this isn't 
an appropriate subject for a technote - people developing partitioning 
software who claim to support A/UX should read the A/UX documentation".

I hope attitudes to A/UX have changed since, but the problem that all these 
people keep bumping into is that software with no claims to support A/UX won't 
even work as "standard MacOS" when vuewed from A/UX.

Perhaps Kent or someone with A/UX responsibilities in DTS would care to 
reconsider producing a technote in this area?
