Hi Johnny,
thank you for your and all centos team works.
Many of us know how much work is needed for building new releases and
maintaining C6 and C7, plus CentOS Stream and modules (Appstream). This is
a huge work for a small team. Again thank you.
For me OL is not an alternative.
As reported in my previous message I'm not worried about how much time is
required to build the new (major/minor) release, it will be ready when it
will be. My major concern is about the "security update blackout" that take
long as the build process.
I would ask to you:
1. Why all security fix are stopped when a new release building process is
started? There is a way or possibility to run the two process in parallel?
So .. when a point release happens .. say 7.8 to 7.9 (just an example ..
could be 6.10 to 6.11 or 8.1 to 8.2, etc)
Those packages are built against EACH other, one at a time. Once we
build the new gcc, new kernel, and new glibc (if they are reqruies) ..
then all the OTHER updated packages are built against those new
libraries.. they therefore need those NEW shared libraries to run. So
the new files have to be released as a set, not individually.
2. When a build process is started and a security fix released there is a
way for your team to "suspend" the building process, release security
updates (for 6/7.x or 8.1) and resume the builing process? I think that
many users (included me) will have less disappointment having security
updates instead of receiving a "signal lost" when building process takes
its way.
It makes no difference if the update is a bugfix update or a security
update. If 500 packages get released at the same time, they have to be
built in a specific order in order to match how they were built in RHEL.
We have to build them, one at a time, then individually test them to
make sure they LINK against the proper new libraries and not older
libraries.
Also any UPDATES released to the new version , after RHEL does the point
release (so updates FOR 7.9 after the 7.9 release) need to wait until
the 7.9 release is done and tested to be built .. as they were built
against RHEL 7.9 and not RHEL 7.8
So, you can't just build items out of order at point release time.
We have to build the 500 packages , in a specific order. We then have to
test the packages, and usually rebuild several of them again for bad
links, etc.
This is the process that takes time .. testing and getting the proper
links to the proper shared libraries.
If we quickly release bad files .. then we have to rebuild them and
re-release them with different versions that RHEL has (because they have
to replace our previuosly BAD release). That is not good for anyone.
Hopefully this answers your question.
Hi Johnny,
thank you for your answer. This is more clear to me now.
Alessandro.
