openSUSE Release Process » openSUSE 13.2 Release

import sys
import solv
pool = solv.Pool()
pool.setarch()

sysrepo = pool.add_repo("@System")
sysrepo.add_rpmdb()

facrepo = pool.add_repo("oss")
facrepo.add_solv(sys.argv[1])

pool.createwhatprovides()

for s in sysrepo.solvables:
    haveit = False
    for s2 in pool.whatprovides(s.nameid):
        if s.repo == s2.repo or s.nameid != s2.nameid:
            continue
        haveit = True
    if haveit:
        continue
    nevr = pool.rel2id(s.nameid, s.evrid, solv.REL_EQ)
    for s2 in pool.whatmatchesdep(solv.SOLVABLE_OBSOLETES, nevr):
        if s.repo == s2.repo:
            continue
        haveit = True
    if haveit:
        continue
    print s.name

is mls' python script to output what is obsolete on his system. This needs to be enhanced to work on testtag versions of all openSUSE distributions and then merge the drop list.
It's best if we create the drop list from scratch all the time to avoid the cleanuporphaneds task

to create a solv file for 13.1 I did

12036  mkdir 13.1
12037  wget http://download.opensuse.org/distribution/13.1/repo/oss/content -O 13.1/content
12038  mkdir -p 13.1/suse/setup/descr
12040  wget http://download.opensuse.org/distribution/13.1/repo/oss/suse/setup/descr/packages.gz -O 13.1/suse/setup/descr/packages.gz
12043  susetags2solv -c 13.1/content -d 13.1/suse/setup/descr/ > 13.1.repo.solv

We need to collect some of them and extend the loop
