device id version _string_?

["Adam J. Richter" <adam@yggdrasil.com>]

	Hello, Keith.

	I was wondering what you think of the idea of having a
short version string for a device ID structure rather than a version number.
The advantage of this is that it allows modified kernels to ensure
that an incompatible version of depmod will complain about an
unknown version string without requiring central coordination to
hand out version numbers or determine an order to them.  It could
also make the naming more mnemonic.  

	For example, let's say Yellow Dog decides to ship an
enhanced version of (future) FireWire ID's.  They might set their
firewire_device_id version string to string to "yellow1" to ensure
that people use a depmod that supports their kernel (or at least get
a warning about it so they can expect firewire hot plugging not to work).
Later, if that format is rolled into the standard kernel or you want
to support it from the stock modutils, you could integrate the code
that handles that particular version string value.
