I'd like to propose the following change to Debian Policy. My writing
style and terminology may need rewording, but the main ideas are
supposed to be:
- - the traditional device names should be used by default
- - the devfs-style names are not the default, but are supported by the
distribution, and so should also be supported by all packages using
(hardcoding) device names
- - if hardcoding device names, both the defvs-style and traditional
names should be checked for, with the traditional names being the
default.
- - ideally, device names should be configurable by the user, though
this isn't required
- - I specified the Linux port, since other kernels may impose a
different device naming policy. I'm not sure if this is the case or
not.

Debian uses the serial devices
<file>/dev/ttyS*</file>. Programs using the old
<file>/dev/cu*</file> devices should be changed to use
