Summary:
What's the point of sup+import?  The "Tracking current" pages say I can always
get an unmodified source tree with that method, but I could always do a full
anoncvs checkout.

Scenario:
I used to have a CVS project called "etc" with all my config files.
I don't think I have a 1.1.1 branch on it, I think I just created it
out of the blue one day.  This makes it a hassle to merge in changes
to NetBSD, which I do manually.  I want to start basing my stuff off
NetBSD so that I can automatically merge changes.

Can I automatically merge changes with the anoncvs method?

I read the document on tracking -current and I decided to do sup+import.
I'm having major problems with sup timing out 90% of the time.
This has made me wonder, is there any real advantage to sup+import?
In the "tracking -current" page they mention I can always build a unmodified
source tree.  But I could always do a clean anoncvs checkout, right?

Thanks for your advice.
