I get this scrolling by in the verbose startup dialog after all el capitan updates:
Aug 4 21:12:44 localhost kernel[0]: Sandbox: launchd(1) System Policy: deny(1) file-write-unlink /private/var/run/dyld_shared_cache_x86_64
Aug 4 21:12:44 localhost kernel[0]: Sandbox: launchd(1) System Policy: deny(1) file-write-flags /private/var/run/dyld_shared_cache_x86_64.map
Aug 4 21:12:24 localhost com.apple.xpc.launchd[1]: Failed to remove file or directory: name = dyld_shared_cache_x86_64, error = 1: Operation not permitted. Further logging suppressed.
From what I understand, these files should be copied from /var/db/dyld to /var/run, but since not even root can delete these files, old caches lie around in that directory:
-rw-r--r-- 1 root daemon 3 4 Aug 21:12 diskarbitrationd.pid
-rw-r--r-- 1 root wheel 437135970 9 Jul 22:12 dyld_shared_cache_x86_64
-rw-r--r-- 1 root wheel 98849 9 Jul 22:12 dyld_shared_cache_x86_64.map
Of course you can't delete them with sudo either.
How does this affect the system, though?
