Source: hostname
Version: 3.15+nmu1
Tag: patch
The hostname tool depends on libnsl and associated headers
which prevents it from compiling on musl (and possibly on
other systems). The observable behaviour of the tool should
not change with the attached patch on a glibc based system.

+hostname (3.15+nmu1) UNRELEASED; urgency=medium
+
+ * Non-maintainer upload.
+ * Fixes build on musl libc.
+ * Use _GNU_SOURCE feature test macro, instead of glibc internal __USE_GNU.
+ * Use getdomainname instead of yp_get_default_domain because it is more
+ widely available and avoids the -lnsl dependency.
+ * localnisdomain is kept, even though it should be the same as localdomain,
+ so the behaviour is not changed in case of an error.
