Sometimes, we think it makes it somewhere. The sentience of the beings

I see where you're coming from, but the way -n currently works, when CVS
would have tried to create a directory, it stops before it knows whether
it would have been empty or not.
In other words, under normal operation, the `-d' specified to update
causes all directories to be created locally (except in noexec mode, but
I'll get to that). Then, after CVS has finished with the directory and
all subdirectories and is about to recurse back up a level, when `-P'
was specified, it checks to see if the directory is empty and removes it
if it is.
Now, in noexec mode, the directory never gets created, so CVS never
checks to see if anything would have been checked out underneath it. It
seems necessary to warn the user that the directory (and possibly sub
directories/files) _might_ have been created there since that is
basically the "question" they asked by running the command with `-n'.
Thus the `New directory <dir> -- ignored' message.
The message comes out on stderr, so, as a workaround, you might be able
to ignore it with 2>/dev/null. Alternatively, if there are other
messages you want to see coming out on stderr, you could pipe stderr and
stdout through a filter:
$ cvs -qn up -dP 2>&1 |egrep -v '-- ignored$' |some_script
or the like.
Of course, Ximbiot <http://ximbiot.com> could update CVS to cache the
directory tree properly so -n would do what you'd expect here on a
contract basis.
DISCLAIMER: No warranties or representations. It's not my fault if you
neglected to back up your file system and something I suggested caused
data loss. Read, understand, and test everything I suggest before using
it in a production environment.
