Managing dynamic device naming

Managing dynamic device naming

One important aspect of the device naming problem is that it isn't uniform. There are a number of devices which are completely standard (e.g., /dev/null). There are a number where the permissions don't need to be persistent, because they will be set when the device is opened (ttyp*). There are a number of symlinks. There are a few things that aren't devices but are in /dev (initctl, log). There are a few cases where there are a ton of nodes which follow a pattern (fd*, partitions of disks).

This all means that it's easy to find an entry that justifies just about any idea, but hard to find a design that fits all of the behaviours desired even for the current set of devices.
