In UNIX-like systems we often have more than one way to do things we
need. For example, we can use more portable

   gzip -dc file | tar -xf- 

(some tar-s doesn't have -z option) instead of

   tar -zxf file

with reasonable overhead for context switches or

   gzip -dc

instead of


You know, there are a lot of other real life examples.

One way may be a bit more easier and/or shorter than another one.
The same for 'cp -a'. I have no strong opinion here.
Yes, 'cp -Rp' works fine, no problem.
My intention was to make 'cp -a' *sligtly* easier
for regular use. That's all.
If this benefit doesn't sound reasonable to NetBSD developers,
no problem, I'm fine with 'cp -Rp'.
