From 3608e32cd12295171adbe29b771e8dcbf15195b6 Mon Sep 17 00:00:00 2001
From: Sam James <sam@gentoo.org>

Subject: [PATCH] sys-apps/shadow: port to GNU Hurd

Only build btrfs support (what does that even do for shadow?) on Linux
and avoid collision on /bin/login, as sys-kernel/hurd provides its own.
