Linux - What is the significance of the 'pkg#' suffix on the .run file?
The "pkg#" suffix is used to distinguish between .run files containing
the same driver, but different sets of precompiled kernel interfaces.
If a distribution releases a new kernel after an NVIDIA driver is
released, the current NVIDIA driver can be repackaged to include
a precompiled kernel interface for that newer kernel (in addition
to all the precompiled kernel interfaces that were included in the
previous package of the driver).
.run files with the same version number, but different pkg numbers,
only differ in what precompiled kernel interfaces are included.
Additionally, .run files with higher pkg numbers will contain
everything the .run files with lower .pkg numbers contain.
