+Subject: [PATCH] all: use install(1) to install executables
+
+When the destination file already exists, the current install script
+will overwrite it with the new executable.
+
+However, when the existing executable is a symlink or hardlink to
+something else, like busybox, this effectively overwrites that something
+with the new executable, and thus replaces busybox and all its applets
+with the code for either of the three commands.
+
+We fix that by simply calling install(1). install(1) is sufficiently
+widespread that we don't bother checking for it, as tis is just a
+workaround while waiting for the version bump that will eventually fix
+it for good.
