I know it's supposed to be a world of arbitrary LBA, but ensuring slices
(partitions) are on perfect cylinder boundaries is ideal, and should be
the default.  I guess one could give the option to use an alternative
heads/sector size in the "druid," but I'd default to what the disk uses
(in the case it does not already have a disk label / partition table,
which we already respect if it does).

Just remember that 64GB = 59.6GiB.  And then there are also spare cells.

Of course, if we're going to start talking SSDs, we should _avoid_
creating swap on a SSD while we're at it.  ;)

Whether it's /export or some other TLD than /home, the idea is to always
have the "source" located outside of /home, because /home may be
automounted.  To this day, I still use the nomenclature ...  

  /export/(server)/(resource) -> /home/(domain)/(resource)

The "server" in the /export source tells me the server.  The "domain" in
the /home mount where all the automounter maps for that domain will will
mount.  In the server itself, I will use a local automounter map with a
bind mount to override the domain automounter map that uses a network
filesystem protocol when the store is local to the server itself.

As a fallback, such as on any workstation, I just create (and bind
mount):  
  /export/local -> /home/local
