+Subject: [PATCH 1/4] nspawn: Don't pass uid mount option for devpts
+
+Mounting devpts with a uid breaks pty allocation with recent glibc
+versions, which expect that the kernel will set the correct owner for
+user-allocated ptys.
+
+The kernel seems to be smart enough to use the correct uid for root when
+we switch to a user namespace.
+
+This resolves #337.
