Almost.  The exception is that you may remain on an older hardware
enablement stack until you take explicit action:

No, this has nothing to do with the enablement stack stuff.  If you
aren't seeing /etc/lsb-release being brought up to date, then your
upgrades aren't actually happening and you need to investigate why.

In general that's not possible, because not all the packages from older
point releases remain available from the networked archive.  To install
an older point release, you need to install from corresponding
installation media.

debootstrap will bootstrap from trusty without trusty-updates, which
corresponds to 14.04(.0).  You can then apply updates on top of that,
which will get you to whatever is latest (not necessarily the latest
point release, but rather rolling stable updates).  You can't get to a
specific point release this way.

deboostrap eg : 14.04.1

2016-03-09 Thread Master
Hello,
I am wondering two things that I am missing for my own understanding.
First thing is when I use two live installer for 14.04.1 and 14.04.2, later on 
during updates/upgrades, does my two installation 14.04.1 and 14.04.2 diverge 
or converge?Does installed 14.04(.x) end up being all the sames after packages 
apt-get update/(dist?-)upgrade?What I mean is the DISTRIB_DESCRIPTION of 
/etc/lsb-release remains 14.04.1 for one and 14.04.2 for the other.So does the 
packages level also remains 'in-line' with that support release version?And how 
much value has the DISTRIB_DESCRIPTION compare to update/(dist?-)upgrade?One 
could say I could have diff my packages in both installations, but I prefer to 
have a good answer from someone that really know the answer or point me 
documentations on the subject.
Because my second things is that I am trying to debootstrap a specific ubuntu 
version eg : 14.04.1 for testing purposes.But I am not sure how to accomplish 
that, if even possible.I always get DISTRIB_DESCRIPTION at 14.04 and I am not 
sure if it means 14.04(.0) or 14.04(.4 latest?)?
Thanks in advance,Best Regards,Mickaƫl.
