+Subject: [PATCH hurd 1/4] Add a new exec_exec_file_name RPC
+
+* hurd/exec.defs (exec_exec_file_name): New RPC.
+(exec_exec): Label as deprecated.
+* doc/hurd.texi: Updated.
+* exec/exec.c (S_exec_exec_file_name): New function.
+(S_exec_exec): Label as deprecated.
+(do_exec): Add argument.
+* exec/hashexec.c (check_hashbang): Add argument.
+Don't guess the file name if file_name_exec is set.
+* exec/priv.h (check_hashbang): Add argument.

+Subject: [PATCH hurd 4/4] This patch is an amendment of
+ exec_filename_exec.patch.
+
+If file_name_exec is not given, check_hashbang will try to locate the
+file. If argv[0] contains a '/', the file path is assumed to be
+absolute and it will try to open the file. Otherwise, the file is
+searched in the PATH. In either case, the resulting file identity port
+is compared to the identity port of the original file handle passed to
+check_hashbang.
+
+exec_filename_exec.patch explicitly provides the script files path in
+file_name_exec. According to the comment, if this path is provided, it
+is assumed to be the path to the script file and no attempt at
+locating the script file is done. However, the identity ports are
+still compared. This cannot succeed if fakeroot or chroot is used,
+because the process doing the exec and thus the initial file lookup is
+running in the chrooted environment, while the exec server is not.
+
+Fix this by skipping the identity test if file_name_exec is provided.
+
+* exec/hashexec.c (check_hashbang): Skip the file identity test if the
+  file_name_exec is provided.
