It simplifies the boot process and eliminates a whole class of I'm not sure I get that point. Why is the boot process simplified if now every script has to check for it's run directory and potentially create it or having to introduce fake boot scripts, which do nothing but create a run directory. > potential directory traversal races that you otherwise have to think > about.

I doubt, that the boot process will be faster if I have to fork a shell and create a run directory. And the /var/run directory is not something that is constantly written at, so I also doubt that it will buy you much of your flash drive life. But let's be pragmatic, if we want to support both methods, why should we have to touch dozens (if not hundreds) of init script if I can do the same with 10 lines of shell code (which does the backup/restore) and this problem is solved today. I don't think this solution is less elegant then fixing a myriad of init scripts. I'm even willing to write such a patch and post it here for review.
