Hallo!
In the past I used sup for keeping my pkgsrc actual.
The problem is, that a whole sup run takes about 
one hour, regardless is the last sup was one week or ome
month ago. During this hour there is heavy traffic in the
 first 15 to 20min and after this nearly no traffic is 
on the line.

I want now test if cvs is faster for me. Do I have to make 
a checkout first:
cvs checkout -PA pkgsrc
or can I start with
cvs -d $CVSROOT update -PAd pkgsrc
as described in the NetBSD-Guide?

Another question regarding the last line of this section in the guide.
Do I really have to make the make clean before every update? 
 
Ciao , Frank .
