I've had requests to move the super down to 64k to make room for
bootloaders, which may not matter for sparc, but I don't really plan
on different locations for different arches.
The Sun disk label sits in the first 512 bytes and the boot loader
block sits in the second 512 bytes.
I think leaving even more space is a good idea for several reasons.
Yep. I chose 32K unused space in the prototype filesystem I wrote [1,
2.4 era]. I'm pretty sure I got that number from some other filesystem,
maybe even some NTFS incarnation. It's just good practice to avoid the
first and last "chunks" of a partition, FSVO chunk.
