+
+Musl doesn't implement GLOB_TILDE, which is used by i3 when expanding paths.
+
+This patch replaces usage of GLOB_TILDE in glob() by replacing tilde
+with the content of $HOME - if set - manually.
+
+As mentioned in the i3 bugtracker this is an issue that should be solved by musl.
+
+A patch has been sent to musl upstream, but it hasn't been merged yet:
