J'ai pose la question a aj (Anthony Towns) sur IRC:

<CQ> is there a way to see whether a debian box is at 2.2r2 or r3?  That
   question came up on the debian-fr list
<aj> CQ: compare the versions in /var/lib/dpkg/status against the 
versions in
   the Packages file
<aj> CQ: (2.2r2 + security updates = 2.2r3, in most cases, so there's 
not
   really an easier way)
<aj> CQ: point apt at stable, and do a dist-upgrade? :)
<CQ> aj- can't /etc/debian_version include that info, or make a 
separate file
   where it exists?  I can see teh need to be able to go to a machine 
and see
   what level of upgrading it's at...
<aj> CQ: easier to write a script to do what i said aboce, really; more
   accurate too
CQ> hmmm... anyon here have a script to do that?
<aj> CQ: awk '/^Package:/ {P=$2} /^Version:/ {print P, $2}' | sort  > 
a.txt
<Omnic> bod, file an RC
<aj> CQ: run that on both Packages.gz and on /var/lib/dpkg/status
<aj> CQ: then run diff status.txt pkgs.txt | grep '^[<>]' | sort, and 
the <'s
   are the versions you have installed that aren't up to date
<aj> CQ: then run diff status.txt pkgs.txt | grep '^[<]' | sort, and 
the <'s
   are the versions you have installed that aren't up to date
<aj> would be better actually
<CQ> where is Packages.gz?
<aj> from the ftp site
<aj> debian/dists/potato/main/binary-i386/Packages.gz
<CQ> so you can really only compare it to main or non-us etc. not all 
at once.
<aj> cat them together first
<weasel> how about using available rather than packages?
<aj> weasel: as long as you run dselect update first; then you 
might's'well
   just run apt-get dist-upgrade as well
<aj> CQ: what's wrong with "apt-get update; apt-get dist-upgrade -u" ?
<CQ> aj- true...
<CQ> aj- ok if I repost this conversation to debian-fr? 
<aj> CQ: yeah, sure
<aj> CQ: packages that are removed but not purged could get listed, btw

...donc il parait que c'est soit un script pour comparer les fichiers 
(apres un 'dselect update' pour mettre a jour le fichier 'available' 
(cette machine est sur 'testing':
/tmp > cat /etc/debian_version 
testing/unstable
/tmp > sudo dselect update
/tmp > cat /var/lib/dpkg/status | awk '/^Package:/ {P=$2} /^Version:/
          {print P, $2}' | sort > a.txt 
/tmp > cat /var/lib/dpkg/available | awk '/^Package:/ {P=$2} 
/^Version:/
          {print P, $2}' | sort > b.txt
/tmp > diff a.txt b.txt | grep '^[<]' | sort                            
               ...etc...

...ou juste regarde /etc/apt/sources.list ou /etc/debian_version pour 
voir si la machine est sur 'stable' et faire:
apt-get update; apt-get dist-upgrade -u

Voila...

a+
