Bug#603036: lvm2: fails to install due to incorrect dependencies in init.d LSB header

thanks

There are two ways to fix this issue.  One is to change the package
dependencies of lvm2 to depend on udev, the other is to change the
init.d script dependency on udev from a hard to a soft dependency.

Hard dependencies are required when the package is installed, while
soft dependencies only define ordering if the two packages in question
are both installed.

I believe switching to a soft dependency is the correct solution, as
the package relations receive more though in Debian these days than
the init.d script relations.

Here is a patch to implement this change.

Given that udev is installed on most Debian systems, it can be argued
that this issue is not release critical.  I expect incorrect udev
relationship to be RC for kfreebsd but given that lvm2 do not work on
kfreebsd, it is purely ac itademic in this case.

Happy hacking,
