[[!meta title="Is there a 64-bit version?"]]
There are plans for 64-bit kernelland with 32-bit userland, which will notably
permit to efficiently make use of more than 2 GiB memory and provide 4 GiB
userland addressing space.
A 64-bit GNU/Hurd is also coming soon! Hurd developers ported GNUMach to
64-bit some time ago. Then they started making significant progress
on the x86_64 userland port in Feb 2023. As of May 2023, the 64-bit
port works well enough to start all the essential Hurd servers, run
/bin/sh, establish TCP/IP connections, and compile C. We are currently building
64-bit packages. We plan on supporting both a 32-bit and 64-bit Debian
GNU/Hurd, only not both at the same time. However, there is no plan to fix the
year 2038 concern on a 32-bit system.
That being said, you can always run a 32-bit version on a 64-bit machine, it
just works, processes are just limited to a couple GiB available memory.
