So why should we be installing an OpenSolaris distribution in to a
partition type that belongs to DOS/Windows ?
That is not entirely correct. Extended partition, IIRC, allows you
to break the limit of 4 primary partition per disk. Once the extended
partition is created another 4 partitions can be nested inside it.
And so on. Think Russian dolls.
Yes but the partition IDs that this project is suggesting be used are
explicitly tagged as being for DOS or Windows.
Just to clarify more:
A partition tagged with EXTDOS or EXTLBA will contain another
partition table. This is
called an EBR - Extended Boot Record. This in turn can contain upto 4
slots just like the
MBR. So we'd be able to define a partition entry of type Solaris2 in
one slot and allocate
space to it. The convention is to use the first slot for an actual
partition and use the second
slot to point to another Extended partition containing another EBR -
Russian Dolls, Linked
List ...

There are also Linux Extended (85) partitions as well, so why not
(ab)use those too ?
There are several other values tagged as being "extended" partitions,
if the list I'm looking at is upto date there at at least another 8 in
addition to the two DOS/Windows ones listed above that the Linux
Extended one.
Lets look at this the other way would it be acceptable for some
version of Windows or Linux to install itself into a slice in a
Solaris VTOC inside a Solaris tagged fdisk partition ?
