+Subject: [PATCH] util/grub.d/25_bli.in: fix shebang on unmerged-usr
+
+On an unmerged-usr system, grub-mkconfig errors out with the following
+error due to /usr/bin/sh not existing:
+
+/usr/sbin/grub-mkconfig: /etc/grub.d/25_bli: /usr/bin/sh: bad interpreter: No such file or directory
+
+Use a /bin/sh shebang to fix the error as well as match the other
+existing files.
