Hi,
On my antiX 19 computer, I was having problems booting. Since I had a 4.19 kernel, I thought a 5 series kernel might boot OK.When I looked at the choices available, there were several 5.6.0.0.bpo kernels, including (I thought) 2 different real time ones.
I noticed that the real time kernel was not titled antix, so I installed an antix 5.6 kernel (5.6.10) in addition, which is not (as I recall) a real time kernel.
Both boot the computer in a very similar fashion.
I am puzzled by the offering of a kernel NOT labelled as antiX – is it also a nosystemd version?
If both are nonsystemd, why does the real time kernel not say antix?
Finally, as a “regular end user”, will a real time kernel offer me any benefits or cause me any harm?
Thanks for any comments.

I had no idea what you were talking about when I first came across this thread. So I searched & read up on it. It was very interesting. (Thanks for bringing it up.)
The antiX kernels are kernels anticapitalista has compiled (I believe he compiles them all) for antiX specifically. If you searched for all kernels, then you’d find those offered in the Debian repositories, too.
But the real-time kernels (I believe I understand it sufficiently) are for specific-use, even single-application-use (or a limited number of applications run, and only specific ones — so that nothing can bog-down mission-critical processes). Like robotics, high-tech scientific research, running a manufacturing industrial set-up, professional audio-video, where one needs to know that nothing can interrupt or slow down critical work, specifically-timed processing and precision valued above all else. If you were to set up a single-purpose pc, it might run better with an RT kernel, if you knew how to configure everything. But a general-purpose pc would run best with the non-real-time (traditional) linux kernel. The RT kernel might run slower on a general-purpose pc, than the regular kernel, just by virtue of how it is built to work.
(That’s what I got out of my 20 minutes worth of reading about RT kernels online.)
This is where I learned the most:

Thanks christophe,
I kind of assumed that must be the case.
However, I figured it would be harmless since I could try it and if I didn’t like it use another kernel. Also, I wondered if this would work, because I wasn’t sure if it was a systemd kernel.
I haven’t noted any differences – between the antix 5.6.10 and 5.6.0.0 PREEMPT-RT kernels so far. Booting occurs hit and miss with all three of the installed kernels so far. Once booted things perform the same (crudely measured).
But at worse after a few reboots, it does boot.
Now, if I could get my mouse/touchpad/cursor not to jump unpredictably…(sigh).
