However, +Linux' and the GNU Hurd's [[ABI]]'s have sufficiently diverged, so that this is +not easy to do. That's why you can't currently install a system in this way, +but you need a separate installation of the userspace suited for the Linux +kernel, or the GNU Hurd. diff --git a/hurd/faq/share_userspace.mdwn b/hurd/faq/share_userspace.mdwn deleted file mode 100644 index 3dbe2d6d..00000000 --- a/hurd/faq/share_userspace.mdwn +++ /dev/null @@ -1,14 +0,0 @@ -[[!meta copyright="Copyright © 2009 Free Software Foundation, Inc."]] - -[[!meta license="""[[!toggle id="license" text="GFDL 1.2+"]][[!toggleable -id="license" text="Permission is granted to copy, distribute and/or modify this -document under the terms of the GNU Free Documentation License, Version 1.2 or -any later version published by the Free Software Foundation; with no Invariant -Sections, no Front-Cover Texts, and no Back-Cover Texts.
