+Date: Thu, 2 Apr 2015 23:03:46 +0200
+Subject: [PATCH] *: Switch to POSIX utmpx API
+
+UTMP is SVID legacy, UTMPX is mandated by POSIX.
+
+Glibc and uClibc have identical layout of UTMP and UTMPX, both of these
+libc treat _PATH_UTMPX as _PATH_UTMP so from a user-perspective nothing
+changes except the names of the API entrypoints.
