+Subject: [PATCH] Link with fts library
+
+Nnn depends on the non-standard fts functions to traverse the file
+system. Most BSD systems provide them out of the box and on
+GNU/Linux systems, they are part of glibc.
+
+On Serenity, they are provided by a separate library (the libfts port)
+that was originally intended for musl-based Linux systems.
+This patch makes nnn link against this library.
