[OpenIndiana-discuss] trying to get 4K aligned root pool on ESX

[Steve Goldthorpe]

Hmm seems like /255/63 is so embedded that either VMware or illumos is
overriding what I put in the vmdk file.  I managed to get an aligned msdos
partition by using parted, however still haven't managed to get an aligned
solaris partition within that (always seems to pick up the /255/63 geometry
and insist on cylinder alignment)...
