+Subject: [PATCH hurd 05/14] boot: remove unused function
+ `boot_script_read_file'
+
+The unused function `boot_script_read_file' requires access to the
+default pager, which is privileged.
+
+* boot/boot.c (defpager): Remove now unused variable.
+(boot_script_read_file): Remove unused function.
+(main): Do not acquire port to the default pager.
+* boot/boot_script.h (boot_script_read_file): Remove declaration.
