Or should we begin to > officially remove support for it? Keeping this to i686-linux specifically, what generation of hardware supports i686 but not x86_64? Some (very) quick checking on wikipedia suggests that the x60 from 2006 was either 32-bit or 64-bit, and I believe there was an atom chip from 2015 that was 32-bit. Specifically, that makes the newest hardware (at least from the CPU perspective) 10 years old at least. Perhaps a different question, what software _available in Guix_ is supported by i686 that isn't supported by x86_64? In terms of side-stepping the question, do we have enough x86_64 hardware to continue to support i686 without degrading support for x86_64? (I ask this seriously, although I'm pretty certain the answer is we're well covered on that front.) --=20 Efraim Flashner =D7=A8=D7=A0=D7=A9=D7=9C=D7=A4 = =D7=9D=D7=99=D7=A8=D7=A4=D7=90 GPG key =3D A28B F40C 3E55 1372 662D 14F7 41AA E7DC CA3D 8351 Confidentiality cannot be guaranteed on emails sent or received unencrypted --Yur0IxwG1OAuI9Jl Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEoov0DD5VE3JmLRT3Qarn3Mo9g1EFAmamvO4ACgkQQarn3Mo9 g1G6HxAAwr7Kv6z13z5VYoFeZSAKl0pUYlu1EOvUJHUJ6zFPUufUMxIOlXzCc0ix qdRHeJcMlx5p/wgcyqpFCikaPJpHl6ZkE+iiPw/VGEx5+DBwQHdQoG2WIWpqL0VG JmmdIEJeFH6v3NGnQ7jG3V4G7wXW0mFSR0z5fsjQ5VqTWaNWHmWl6bzksXneJA6J 0wk0uaTbYNtNxVXTBPtGWmS5dxGgULgAEXCXo567KVftY0roUtyOO5mwIkmHnp16 +tXCtjOwwSO+L4k1SRib1ie7joHYcnltusk/fi+jdr5/GzJUfgUmekcj9Hxm2VxK 2Cqy+fZx+yGlAEKFhzQNwWNc7D0hFZxj9cAMHQAro3PXieBP9jOhihEE+sSYUxa9 Aj/pOklhZlPHxYSuzrm+5tCx9dBWoK2i0tOzG0VY178xOWNmguJfpyWudzdoIGVj j6xWpBHrL0OJ5OiW1/vQB0Um58ROmZPOb+VWMzeZ614omZwTXSfOOrG5aCRxg+I6 wcjOJGOFJdOaTU7/pNVJJDSdwXgPxHucygVbSLvMTHxTVnXHXmg/NtrIyhgRC8h+ WEkxce7AVw9MxRT3PfgaiDGlhRHkYO9mRmcI76uL/hiOGwGbQir404YhcHBx421K HYPUYZGYVXjuVyBCtR2WQJ34oPjXCPCTov0hSezbIP9zrVAwOUY= =8+ZS -----END PGP SIGNATURE----- --Yur0IxwG1OAuI9Jl--
