Yes.  Please remember that device locking is done in user land, by files
named "LCK..ttyS*".  If you have multiple names for the same device,
programs won't notice that "ttyS0" is already in use, if someone else has
"cua0" locked via the "LCK..cua0" lock file.

This is *exactly* what got us into this mess - we have to get rid of the
stupid idea of having multiple names for the very same device *FAST*.

It's a support nightmare (I'm the "a getty maintainer" Tytso mentioned who
wanted cua* support dropped ASAP).

I think Ted's idea is very good.  We have to really hammer into people
that cua* devices are deprecated, and that only works if you flood them
with warning messages all over (I have been *telling* everybody this for
years, but this wasn't enough).
