Hi all,
<br>
<blockquote type="cite">I have completed a new build based on
12.04.2 and it looks good so far.

This could be RC2 if we decide to make this extra step towards
Secure Boot. <br>
I would like to hear more opinions about our options here.
Hamish proposed another option on IRC yesterday:
<br>
4. Release RC1 as Final and do a 6.5.1 with the 12.04.2 Xubuntu
base after a month or so, when more feedback will be available.

<br>
from a testing point of view, you have to say, where are the
risks? e.g. What set of users and hardware are affected by the
changes in 12.04.2 ?
<br>
</blockquote>
<br>
Until RC1 we used Xubuntu 12.04.1 base iso and during <b>all</b>
our builds we used "apt-get upgrade".<br>
This means all updates until the day we built RC1 are included
(except kernel updates that were kept back to protect chroot
environment)<br>
The new 12.04.2 base iso brings in updates that were released the
last couple of days (Qt4, openJDK updates and a new kernel)<br>
The new kernel (3.2.0-37) brings support for Secure Boot and I
seriously doubt that it would affect any software of our stack.<br>
OpenJDK update brings in the last <b>very critical</b> java patches
that so much noise was made around the internet the last weeks. My
opinion is that this is a serious security update and we should ship
with it.<br>
Regarding Qt4 updates, small part of our stack is built on Qt and we
can test those applications to check that they are not affected.<br>

<br>
</blockquote>
<br>
Regarding hardware, I am not sure we ever tested on specific
hardware. I feel that we always trust Ubuntu on this area. Why
should this change now?<br>

<br>
internally, it is unlikely that application layer software is
affected much by
<br>
a tiny point change like that, but what might the interactions be?
<br>
Are there changes that effect any of the software stacks?
<br>

<br>
I think this is covered above.<br>
<br>
<blockquote

type="cite">The rote way to test is to mechanically re-examine all
bugs, and
<br>
re-examine all features, and re-examine all quickstarts, when
there
<br>
is a platform change.. This is labor intensive and as noted, we
dont
<br>
have the labor available to do that..
<br>

<br>
I understand that we lack on the testing side, and yes we need more
testers to make all the quality checks needed.<br>

<br>
It is always smart to characterize the nature of the delta, and
use
<br>
insight to try to find where bugs and problems are likely to be...
<br>
Since Ubuntu Linux and the software on the Live is very complex,
<br>
I welcome the ideas of others to make good decisions about testing
<br>
to acheive quality, and decisions about change to lessen risk to
quality. <br>
</blockquote>
<br>
I feel that since testing was only done so far by a small number of
users, it would not be hard to run one more round of testing before
release, but I really want to hear everybody’s opinion on this.<br>
