I think that I now understand the "black-magic part", also the
"/etc/lsb-release" :)
in: /usr/lib/python2.7/dist-packages/lsb_release.py
this doesn't help :
32 RELEASE_CODENAME_LOOKUP = {
33 '1' : 'jessie',
34 # '2' : 'ascii',
35 '2.1' : 'ascii',
36 # '1.3' : 'bo',
37 # '2.0' : 'hamm',
38 # '2.1' : 'slink',
39 # '2.2' : 'potato',
40 # '3.0' : 'woody',
41 # '3.1' : 'sarge',
42 # '4.0' : 'etch',
43 # '5.0' : 'lenny',
44 # '6.0' : 'squeeze',
45 # '7' : 'wheezy',
46 # '8' : 'jessie',
47 }
Initial function:
371 def get_distro_information():
372 lsbinfo = get_lsb_information()
373 # OS is only used inside guess_devuan_release anyway
374 for key in ('ID', 'RELEASE', 'CODENAME', 'DESCRIPTION',):
375 if key not in lsbinfo:
376 distinfo = guess_devuan_release()
377 distinfo.update(lsbinfo)
378 return distinfo
379 else:
380 return lsbinfo
I think Its guessed: :)

>>> import lsb_release
>>> distinfo = lsb_release.get_distro_information()
>>> print(distinfo.get('RELEASE', 'n/a'))
2.0
>>> lsb_release.guess_release_from_apt()
{'origin': u'Devuan', 'suite': u'stable', 'version': u'2.0', 'component':
u'main', 'label': u'Devuan'}
You see here the '2.0' String, and it comes from the funtion
guess_release_from_apt().. like you can see above..
The guess_release_from_apt() function:
228 def guess_release_from_apt(origin='Devuan', component='main',
229 ignoresuites=('experimental'),
230 label='Devuan',
231 alternate_olabels={'Devuan
Ports':'packages.devuan.org'}):
232 releases = parse_apt_policy()
233
234 if not releases:
235 return None
236
237 # We only care about the specified origin, component, and label
238 releases = [x for x in releases if (
239 x[1].get('origin', '') == origin and
240 x[1].get('component', '') == component and
241 x[1].get('label', '') == label) or (
242 x[1].get('origin', '') in alternate_olabels and
243 x[1].get('label', '') ==
alternate_olabels.get(x[1].get('origin', '')))]
244
245 # Check again to make sure we didn't wipe out all of the releases
246 if not releases:
247 return None
248
249 releases.sort(key=lambda tuple: tuple[0],reverse=True)
250
251 # We've sorted the list by descending priority, so the first entry
should
252 # be the "main" release in use on the system
253
254 max_priority = releases[0][0]
255 releases = [x for x in releases if x[0] == max_priority]
256 releases.sort(key=release_index)
257
258 return releases[0][1]
I am afraid that this info, you already know..
I am not a python guy( I love the Lua simplicity way :) ), I can't help.. :(
Best Regards,
