[Pkg-sysvinit-devel] installation-manual: Should it suggests to switch to run level 1 and back?

  http://www.debian.org/releases/stable/i386/ch07s02.html.en is
section 7.2, Mounting encrypted volumes.  From Chapter 7, Booting Into
Your New Debian System.  
The following assumes that this section has no substantial changes
in the squeeze manual.

  Quoting the bottom of section 7.2:

      If any volume holding noncritical system files could not be
    mounted (/usr or /var), the system should still boot and you
    should be able to mount the volumes manually like in the
    previous case. However, you will also need to (re)start any
    services usually running in your default runlevel because it
    is very likely that they were not started. The easiest way to
    achieve this is by switching to the first runlevel and back by

        # init 1

    at the shell prompt and pressing Control+D when asked for the
    root password.

That qoutation doesn't fully match the following quote, which is taken
from the warnings section of man init(8):

     On a Debian system, entering runlevel 1 causes  all  processes
     to  be  killed  except  for kernel threads and the script that
     does the killing and other processes in  its  session.   As  a
     consequence  of  this, it isn't safe to return from runlevel 1
     to a multi-user runlevel: daemons that were  started  in  run-
     level S and are needed for normal operation are no longer run-
     ning.  The system should be rebooted.

1. AM I right that strictly speaking, there are cases where the
   `easiest way' will not work?
2. Should the installation manual be modified?
