And not having the intermediate layer doesn't give you the additional
fragmentation headache; that's a problem when assigned fixed bits of
storage to the filesystem and when you do not allow the filesystem to
know about the layering (not sure what AIX allows there).
"Headache?" I'm not sure I follow. You just assign PPs to LVs. The
assignment is essentially arbitrary, and is normally just done
automatically -- the OS chooses a strategy for allocating them and can
try to fit contiguous ones if it wants to.
The only "headache" I see here is that if you have Solaris UFS
partitions, and you didn't plan for slice 0 to grow past (say) 3GB but
you now need it to do that in order to perform an upgrade, you're in
pretty deep.
This is one of the areas where Solaris has been behind other OSs out-
of-the-box, IMO. Thankfully, products like Veritas Volume Manager
(takes $$$) have been available, although it doesn't solve needing to
expand "/" without careful planning.
ZFS looks very interesting in this regard.
