So I gather that the device is ALWAYS used in "raw" mode, so there
is really no need for an explicit "r" designation. Getting rid of
the "r" versions cleans things up a lot, so it works for me...
Regarding the ".[0-3]" extensions, I am still perplexed. It sounds
like the mode bits are overloaded with the [en] designations, as:
/dev/sa0.0 Corresponds to sub-mode 00 (i.e., /dev/sa0)
/dev/sa0.1 Corresponds to sub-mode 01 (i.e., /dev/nsa0)
/dev/sa0.2 Corresponds to sub-mode 10 (i.e., /dev/esa0)
But if that's true, I don't understand how there can be names such as
ersa0.0. Finally, mode 3 is actually being created by MAKEDEV, but it
is not mentioned as a possibility by the man page. What's going on?
