This package contains a script which is linked via the alternatives subsystem to /usr/sbin/policy-rc.d. This script looks for a local policy-rc.d script in /usr/local and /etc, providing a policy- and FHS-compliant way to interface invoke-rc.d with a local script.
Without this package, a local admin wanting to cleanly interface with invoke-rc.d is forced to drop a local binary to /usr/sbin and/or manually interface with the alternatives system. Both ways of doing this are clumsy and error-prone, so this package offers a clean way of interfacing with sysvrc and file-rc.
Since there are at least two packages containing their own version of invoke-rc.d, having a search path policy for policy-rc.d can be messy and is prone to be unstructured and uncoordinated.
Hence, having a dedicated package is the clean way of doing things.
This package has its upstream sources maintained in the Debian project, so there is no upstream URL.
