+Subject: [PATCH 4/4] misc: Choose a longer arbitrary line length.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This allows running specifying a `getty' in the GNU Guix store.
+
+* misc/getttyent.c (MAXLINELENGTH): Use 512 (instead of 100) as
+another "great" arbitrary limit.
