 - it uses a different `bindir` (prefixed with `/data/data/com.termux/files/`)
 - it uses slightly different architecture names than Debian
+
+## Conventional file names, Debian, and ARMv6
+
+On Debian, both ARMv6 and ARMv7 have the same architecture name: `armhf`.
+
+If you use `{{.ConventionalFileName}}`, and build for both architectures, you'll
+get duplicated file names.
+
+You can go around that with something like this:
+
+```yaml
+# .goreleaser.yaml
+nfpms:
+  - 
+    # ...
