Actually, it's not so easy, but I tried in this way:

(1) Upgrade some extra packages to optional to satisfy as many dependencies
as possible among optional or higher packages.

(2) Repeat (1) again.

(3) Downgrade some optional packages to extra to eliminate as many conflicts
as possible.

(4) Repeat (3) again.

(5) Downgrade optional packages which depend on extra packages to extra.

(6) Repeat (5) again.

After this I looked at the popularity contest data to make sure some
very popular packages had not been downgraded to extra.

I've put the result in:


Before I get flames... I'm well aware that it's not perfect. Whenever
packages A and B conflict at each other, the result is often that both
packages are downgraded to extra. But we could accept this as a fact
of life and try to upgrade one of them back to optional in woody+1.
In either case it fixes more than one hundred bad dependencies/conflicts.

BTW: The first five priority changes in this file are "mandatory" and
give little room for discussion, they are:

# Packages which conflict with virtual packages provided by standard
# or higher packages:
nullmailer      extra           conflicts with mail-transport-agent (exim)
gidentd         extra           conflicts with ident-server (pidentd)
nullidentd      extra           conflicts with ident-server (pidentd)
# Packages which conflicts with real standard or higher packages:
mailutils       extra           conflicts with mailx
xt              extra           conflicts with bind9-host

If some ftpmaster or the release manager is willing to help fixing wrong
priorities, they are more than welcome to start fixing these five ones.
