It's pretty cheap to get the Hurd running on real hardware. My Thinkpad T43 was maybe $30. The T400 supports SSDs and a max RAM of8 GiB. That should cost you maybe $200 - $300. > Cannot wait to hear how it works out. > Thank you very much for trying it out! > > On Thu, Aug 14, 2025 at 9:23 AM <jbra...@dismail.de> wrote: > > August 14, 2025 at 11:32 AM, "Milos Nikic" <nikic.mi...@gmail.com > > mailto:nikic.mi...@gmail.com?to=%22Milos%20Nikic%22%20%3Cnikic.milos%40gmail.com%3E > > wrote: > > > > > Hey Joshua, > > > > No you didn't do anything wrong. > > > > The tooling is not there yet.
