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).
