SLE vs openSUSE

openSUSE should be very near / equal to SLE basic system.
What does this mean exactly?
Near to SLED or SLES?
What ist the basic system? yast2_basic?
Which packages are the same in both versions?

Best regards.

That some packages in Leap 15 directly come from SLE 15, and maintenance updates for those packages in SLE 15 will get released for Leap 15 too.

Near to SLED or SLES?

I don’t think that question is relevant, as I doubt there is a difference in package versions in SLES and SLED.

What ist the basic system? yast2_basic?

There is no “yast2_basic” I know of. If you mean “yast2_basis”, that’s a pattern containing required yast2 packages, totally unrelated to the basic system.

The basic system is the lower operating system (needed to boot the system), but not e.g. user applications.
There’s not really a strict definition though.

Which packages are the same in both versions?

Well, that depends on the actual package maintainers.
In principle, it is preferred to just take all packages available in SLE unchanged, but the maintainers can of course decide to use a later version from Tumbleweed though.

In practice, things like the kernel, systemd, the compilers, Xorg/Mesa come from SLE, and also GNOME.
Other things may come from openSUSE Tumbleweed to get the latest version, and especially packages that are not available at all in SLE have to come from Tumbleweed like in the past of course.

Not that it really matters much for Leap 15.0, as SLE 15 itself is quite new and completely based upon Tumbleweed a couple of months ago anyway.

If you want to look at the full package list and where each package comes from, you can do so at, in the package 00Meta in the corresponding openSUSE:Leap:XX.X project.

I don’t really know. I’m only a user.

My understanding is that many of the packages are taken straight from SLE. But I think that means the source packages, which are then recompiled for openSUSE. However, there are also many packages that come from Tumbleweed sources.

At this stage, Tumbleweed and SLE 15 are probably not too far apart.

Near to SLED or SLES?

I suppose that depends on whether you install openSUSE as a desktop or as a server.

Which packages are the same in both versions?

As far as I know, the kernel is from SLE, though perhaps tweaked for openSUSE. The Gnome desktop is similarly from SLE, and thus at on older version than currently in Tumbleweed. However, the KDE Plasma desktop comes from Tumbleweed, probably about what Tumbleweed had a month ago.

Actually, the KDE desktop itself is exacly the same as Tumbleweed currently has.
There wasn’t a new release yet since the last updates to Leap 15 (which was about 2 weeks ago).

Tumbleweed does have newer “KDE Applications” 18.04.1 while Leap 15.0 ships with 17.12.3 (3rd party KDE applications should be about the same, only the latest krusader release has been too late for Leap 15.0).
And Leap 15 uses Qt 5.9 (LTS) as a base, which is coming from SLE, while TW has 5.10.0 and will soon get 5.11.0.

You could take a look at the Keynote speech of the 2018 openSUSE Conference: <openSUSE Events.

Ok, long time ago.

I saw the slide.
that gives not an exact answer about what is the basic system.

In other words:
What ist the difference between SLE and openSUSE?
Why should i take SLE for money when openSUSE will do the same for me without costs?

Best regards.

The Enterprise line of SuSE products comes with service license agreements for servers (SLES) and desktop installations (SLED). This includes several assurances/disclaimers/certificates of legality/stability/security, if I recall correctly.

The free-for-all openSUSE projects (Leap and Tumbleweed) have no such agreements or disclaimers. Leap and Tumbleweed are free to use »as-is«, but they benefit from SLE-side developments and bugfixes. Cheers!

(Edited to add: I worked for a major government organisation in Germany with one of the largest SLES installations; this organisation even had visits by an external SuSE specialist twice a week; that’s the kind of service you get with enterprise contracts.)
