Comment 1 for bug 461725

Some IRC context:
<soren> I'm just trying to understand if (and if so, how) we know that the loopback device is available once we start going through rc2.d/S* scripts.
<soren> ..since that used to be the case (given that networking ran at rcS.d/S40)
<ttx> ..and some server software kinda expects at least loopback to be up when started.
<ttx> for example, rc2.d/S15dnsmasq
<slangasek> soren: we don't; it's racy; file a bug on upstart
<soren> slangasek: You agree that having lo available in runlevel 2 is a reasonable expectation?
<slangasek> soren: yes, everything that rcS did for us before should still be guaranteed
<slangasek> unfortunately, switching /half/ of our init system has introduced a few race conditions
