Hi!

I spent some more time working on initscripts and the shutdown sequence.

Pretty convincing argument. :)

I'd be happy to get reviews of what is in feature/shutdown_cleanup. It
has been rebased against latest devel and it now uses patches insead of
insserv overrides.

Short log:

    e9c2c4f Prevent memlockd unload on shutdown
    f8b5dff Fix tails-sdmem-on-media-removal initscript header
    93dd8b3 Leave halt and reboot scripts configured


These first three commits should probably be considered as bugfixes.

    ccf5a60 Assert that dependency based boot sequencing is configured
    dd53671 Disable i2p initscript rather than remove it
    32cbde7 Patch initscripts headers instead of fiddling with update-rc.d


These makes `chroot_local-hooks/52-update-rc.d` way nicer and less error
prone.

    fea2ad6 Do not run unecessary scripts during shutdown sequence


This last one allows to win 7-9% of total shutdown time on my test
system (compared to 0.13).
