+Subject: [PATCH] Fix musl compilation error on Alpine
+
+Disruptions between glibc and musl-(not-)predefined feature-test macros led to
+a decision to remove a check for POSIX standards older than 17 years. It makes 
no
+sense to test the existence of a macro that we explicitly define in
+meson.build either (shall we test for _GNU_SOURCE).

+Subject: [PATCH] pkexec: Use realpath when comparing
+ org.freedesktop.policykit.exec.path
+
+This changes the pkexec path that is compared from the original supplied
+path to the path resolved by realpath(3).
+
+That means that "/bin/something" might now be matched as
+"/usr/bin/something", a review of your
+  <annotate key="org.freedesktop.policykit.exec.path">
+actions might be in order.
+
+Fixes: polkit-org/polkit#194
