I hope you folks aren't yet annoyed by my silly questions... Well, now what 
I'm curious about is: I've installed pkgsrc on a machine by fetching the 
pkgsrc tarball from the netbsd.org ftp, and extracted it. According to the 
pkgsrc docs, I can keep it updated by sup; but if I try that, it'll request 
any changes since 1970 for the first time. The machine in question has a 
quite unstable internet connection, and any attempts so far to sup pkgsrc 
failed.

So is there a way to fool sup into thinking that it has recently (when the 
stuff was installed) updated, and it should only request changes since then?
