slink->potato and missing packages

[Michael Stenner <mstenner@phy.duke.edu>]

So I'm upgrading from slink to potato (while it's still unstable so i
can call myself adventurous) and there are a number of packages
missing (from the ftp site, according to apt).  Some of them look
rather important (tcpd, etc).

Two questions:

1) out of curiosity, how does this happen?

2) what do I do about it?  I can just put those packages on hold and
hope on dependency problems arise.  What's the standard solution?

					Thanks,
					 Michael
