+Subject: [PATCH] paths: support merged /usr directory
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In the Linux world, some distribution started to merge:
+- /bin into /usr/bin
+- /sbin into /usr/sbin
+- /lib into /usr/lib
+- /lib64 into /usr/lib64
+
+Some distro go with more extreme approach, merge `/bin`, `/sbin`,
+`/usr/sbin` into `/usr/bin`.
+
+See: https://www.freedesktop.org/wiki/Software/systemd/TheCaseForTheUsrMerge/
+
+If minigalaxy was invoked as:
+
+	/bin/galaxy
+
+We'll see this error:
+

+> gi.repository.GLib.Error: g-io-error-quark: Error opening file /share/minigalaxy/ui/login.ui: No such file or directory
+
+Fix this problem by explicit checking if LAUNCH_DIR is `/bin` or
+`/sbin`.
