Debian Sparc64 port
Rationale for such a port
- Debian currently only supports 64-bit kernels.
- The current userland is 32-bit, but needs a SPARC V9 CPU, which supports 64-bit instructions.
- 32-bit toolchain is not anymore supported upstream.
More and more softwares are dropping 32-bit support
The use of > 4GB per process is not that uncommon those days, especially in scientific computation applications.

If you are currently on debian sparc, you cannot point to sparc64 packages directly. In the meanwhile, you might be able to run it on a chroot. Usual tool for putting together a root filesystem in Debian is debootstrap, but the port is provided by two different suites and debootstrap is not smart enough to cope with it. multistrap can be used to pull from debian-ports mirror.
