cvs log doesn't tell why the warning is needed for the device path,
nor does PR 3617. I understand why it is helpful to make it a full path,
I even understand why it is useful to resolve symbolic links. But I
don't get the purpose of the warning.

I guess the main reason why they are symlinks is because some thought it
was a smart idea on Linux to do. One reason to do that is to avoid
naming conflicts e.g. if you have a volume group called "tty" or "null",
so that it is always possible to access the LVs. Just guessing though.
