If you're driving along a road with parked cars, you slow to a speed where if someone (say a 4 year old child) jumps out you can stop within your reaction time. Anything else is dangerously reckless.

quicklyfrozen · 5 years ago

That's not a realistic goal. Even at 20 MPH, a well timed jump from between parked cars could leave someone closer then your reaction time.

I replied to you in another thread but nonetheless CentOS Stream isn't going to break your binary compatibility for the same reason that RHEL 7.3 doesn't break binary compatibility with RHEL 7.2. CentOS Stream is spiritually always the next minor release of RHEL.

Unless you're the kind of person who pinned to a specific minor version of CentOS (which isn't the default and not supported for very long) you can use CentOS Stream exactly the same as you currently are and it will be a strict improvement for you. Bugfixes, security updates, and new features will come to you before they're either batched for release in the next minor version of RHEL or back-ported to the current supported releases.

quicklyfrozen · 5 years ago

They do specifically mention that some fixes may come to RHEL first.

I'm sure they'll try not to break binary compatibility, but as it appears to be somewhat experimental and targeted to developers, breaking updates may occur. Isn't that the point of this distro -- so such testing can take place before updates are rolled into RHEL?

So, fine for a developer workstation, but I don't see how it can be stable enough to use in production.

I can’t defend cutting support for CentOS 8. That’s super shitty and I don’t really understand the move.

The part I don’t think people really get is that if your goal was to have a fork of RHEL that was as close as possible to RHEL itself in absolute value that CentOS Stream is much better than CentOS is/was. CentOS always tracked far behind RHEL and now CentOS Stream will track closely in front of RHEL.

quicklyfrozen · 5 years ago

CentOS will be useless as a replacement for RHEL. Without the guarantee of binary compatibility, any CentOS Stream update may break your locally installed applications.

And I only recall CentOS significantly trailing RHEL at the major version updates (e.g. 6 and 7). Other updates seem pretty timely, and the major version lag doesn't leave me vulnerable.

I can see this being useful for developers who are building something that needs to be compatible with the next major release of RHEL, but I'm not sure who else it will be useful for.

You act like RHEL 7.1 is a fixed artifact — it’s constantly receiving updates, security patches, and backports. And CentOS always trails behind on those updates so it’s never exactly the same as RHEL either.

This change makes CentOS so much closer to RHEL that it’s weird that people are acting like the opposite is happening.

quicklyfrozen · 5 years ago

That's the whole point -- it's continually receiving updates that never break binary compatibility with existing apps/packages. For example, it's a safe target for vendors to target with binary packages, whereas CentOS stream won't be.

So where do I actually get this upstream (RHEL8) source of say dracut? Because I was reacting to the comment "Red Hat publishes it's sources on https://git.centos.org. Those are then used to build CentOS Linux packages."

quicklyfrozen · 5 years ago

rpmbuild will download the sources listed in the spec file, apply the patches, and execute the build instructions to produce RPM and SRPM packages. The SRPM will contain the "as built" source tree.

For dracut, the spec file defines the source as http://www.kernel.org/pub/linux/utils/boot/dracut/dracut-049...

> Red Hat publishes it's sources on https://git.centos.org. Those are then used to build CentOS Linux packages.

Have you checked if this repo actually works as intended? Because I was wondering if the git repo has RHEL or CentOS sources (or both). So I tried to find out myself instead of just throwing the question out there. It went roughly as follows:

- Let me check the sources of dracut (the RHEL installer) in https://git.centos.org/rpms/dracut. Files: empty, Commits: empty, Forks: empty, Branches and Releases: judging by the names they seem to be CentOS, not RHEL sources. And they're using git.centos.org just as a code dump, not for development. Fair.

- Let's see the actual code.

  git clone https://git.centos.org/rpms/dracut.git
  Cloning into 'dracut'...
  remote: Counting objects: 1673, done.
  remote: Compressing objects: 100% (1632/1632), done.
  remote: Total 1673 (delta 82), reused 1446 (delta 0)
  Receiving objects: 100% (1673/1673), 1.60 MiB | 2.08 MiB/s, done.
  Resolving deltas: 100% (82/82), done.
  warning: remote HEAD refers to nonexistent ref, unable to checkout.

??? There's nothing there.

- Back to the web interface, https://git.centos.org/rpms/dracut/tree/c8 Reading .dracut.metadata, I guess the source is in SOURCES/dracut-049.tar.xz. But browsing the directory https://git.centos.org/rpms/dracut/blob/c8/f/SOURCES lists only patches, not the presumed source dracut-049.tar.xz

- Maybe it's under Releases? Let's check imports/c8/dracut-049-95.git20200804.el8 Clicking the source tree gets me back to the SOURCES dir with only patches, not good. Maybe the floppy-save button? https://git.centos.org/rpms/dracut/archive/imports/c8/dracut... -> 404-Not-Found. https://git.centos.org/rpms/dracut/archive/imports/c8/dracut... -> 404-Not-Found.

I'm not a professional dev, maybe I just don't understand. But is there a way to actually see/browse/download the dracut source code from CentOS 8.3 (let alone RHEL 8.3) from git.centos.org?

quicklyfrozen · 5 years ago

The RPM SPEC file in that repo will have a pointer to the actual upstream sources for the package. This is a typical scenario -- they are not re-hosting all of the sources to build a Linux distro, just the build steps needed to pull, patch, and build upstream sources.

Why would some think excessive Tylenol would be preferable over narcotic pain meds How much Tylenol would a person have to consume over a two month period to permanently damage their liver This is bizarre.

quicklyfrozen · 5 years ago

I know someone who ended up hospitalized from accidentally taking two over-the-counter meds that both contained Tylenol. It just doesn't take that much to cause damage.

"more walkable and friendly to the elderly" are very separate things, usually in conflict. The elderly face disability like arthritis, poor body temperature control, uncertainty about lower leg position or pavement contact, bad vision, bad hearing, confusion, and numerous other troubles. No normal or reasonable amount of "more walkable" is going to work.

They need family members who care. The family members need parking spaces. The fewer steps from bedroom to car, the better. A nice goal would be to have less than 50 feet from bedroom to car.

quicklyfrozen · 5 years ago

From what I've seen with older relatives, if you're able to stay mobile, you'll stay mobile longer and have a better quality of life. I don't think it's impossible to have housing and shops together and still have parking within a reasonable distance -- for example a town center with parking lots a couple blocks from the main street.

Fortunately (except for lawns and the like) water isn't destroyed or lost. Cities can take the output of their sewer systems and put it right back into the water towers. No city does that today, but only because the thought grosses people out, the water is safe and clean enough that they could.

quicklyfrozen · 5 years ago

We don't do it directly, but there are certainly municipal water supplies that are downstream of other town's waste water treatment plants.
