Re: Debian versions
You're configured to follow sid/unstable.
Since things regularly migrate from sid/unstable to testing,
in most regards the installed OS can't tell which you're on, though one
can look at one's APT configuration to see what one is following.
But they may not necessarily be distinguished by what's currently
installed, notably, e.g.
base-files provides /etc/debian-version and /etc/os-release, and at
any given time,
the version of that package, and thus its files, in testing and
unstable may be the same.
That's also why /etc/debian_version may a bit more fittingly accurate,
with form of
codename/sid
notably as, if it's at least reasonably current, APT may be configured to follow
codename, testing, sid, or unstable, and only looking into the APT
configuration, etc.
will distinguish. The case of /etc/os-release is a bit different, and
it may need to satisfy
some additional requirements (e.g. LSB?).
Not long after trixie is released, base-files will be updated in
sid/unstable (currently under freeze)
and will likewise make its way to testing, at which point it will
indicate forky, instead of trixie,
but it won't indicate forky before that.
