I was having some problems with dependency booting starting init
scripts in incorrect sequence as related to voyage-sync.
Specifically, dhclient was able to open its PID and leases files
before voyage-sync completed setting up the tmpfs directories and
then remountro would fail producing the error "

/ is busy." I worked around this by disabling

2.1.4. Dependency booting<br>
<br>
An important improvement in the Debian GNU/Linux boot system is the
introduction of dependency-based boot sequencing and parallel boot.
This feature is enabled by default in new installs and it will be
enabled for upgrades from lenny, if possible.<br>
<br>
This feature is enabled through the use of insserv by sysv-rc to
order init.d scripts based on their declared dependencies[3]. It has
been possible after a sustained effort to adapt all the boot scripts
of packages provided in the distribution as well as the boot system
itself.<br>
<br>
With dependency-based boot sequencing it is also now possible to run
the boot system scripts in parallel which can, under most
circumstances, improve the speed of the boot process. This feature
is enabled by default, in new systems and upgrades, whenever
possible. To disable it specify<br>
<br>
CONCURRENCY=none<br>
<br>
in /etc/default/rcS. For more information on this feature refer to
the information available in /usr/share/doc/insserv/README.Debian.
