-- apply_patchfile patches the kernel to start /sbin/lunchd instead of launchd.  You can remove that, but the idea is that the filesystem looks like this:
-
-/sbin/launchd: an untether exploit that execs /sbin/lunchd; skipped by an already-patched kernel
-/sbin/lunchd: a script that execs /sbin/launchd.real with DYLD_INSERT_LIBRARIES set to the dylibs in /Library/LaunchExtensions; this may be used in the future by MobileSubstrate
-/sbin/launchd.real: the original /sbin/launchd

-This is the lunchd script:
-
-    #!/bin/bash
-    shopt -s nullglob
-    dylibs=$(for dylib in /Library/LaunchExtensions/*.dylib; do echo -n "$dylib:"; done)
-    export DYLD_INSERT_LIBRARIES=${dylibs%:}
-    exec -a /sbin/launchd /sbin/launchd.real
