Here only 71 with the latest TW (i586). Only 59 on a Raspi. On the openSUSE mailing list server, only 40. There are also times when modules are loaded unnecessarily. I think even the 2.2 series kernel had more than four or five modules :-) Much will depend on what you do with your Linux systems, how many you have and how varied they are.

That's a miniserver.
That seems like a lot for a server. Does it have a lot of various hardware peripherals?

If you count the external hard disks... Well, there is the wireless keyboard+touchpad, the UPS, a non powered USB hub for the hard disks... Those are the hardware additions. Hardware wise, it is just a minipc box, an msi cubi N. -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)

On the leap 15.5 box (desktop) I just installed yesterday - 70 modules. Quite a few are superfluous though - e.g. floppy :-) A regular server - 58 modules, which includes maybe 20-25 ipv6 and netfilter modules. Your mini server has more about 140 more than that, I wonder what they all are. https://paste.opensuse.org/pastes/7328ab3437cf -- Per Jessen, Zürich (12.9°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes

well, the role makes it a server, not the hardware ;-) A media server, actually, I forgot. So it has keyboard, display, sound...

Huh, I intended to send mail from the beta-laptop, but I had to go to the other machine to get the miniserver data. So I try now to send from beta, lets see if Thunderbid mail out works. -- Cheers/Saludos Carlos E. R. (testing openSUSE Leap 15.4, at Beta)

I wish I had to go to "the other machine" every time I needed some data, that would make me a lot slimmer :-) -- Per Jessen, Zürich (12.2°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes

Nah, it is way more prosaic than that :-D The miniserver doesn't allow ssh via password, only by shared keys; and I don't have the keys in this test install. So I saved mail as draft and opened it again in desktop, pasted data from ssh to miniserver, then sent instead of saving as draft and opening it again on Laptop. (which is too long to explain, so I simply said "going to the other machine" ;-) ) All the time sat in my Ikea chair, only rotating it 30 degrees or so. No walking. For that, I have a featureless static elliptic bike on the next room, with my old laptop (which lost its second battery) sitting in front of the bike on top of a stack of plastic storage boxes, which I use to play videos from the Montalbano serial while I exercise. :-D Actually, the home folder of this Beta install I cloned from the Beta install (15.0) of that old laptop. That's why I have Thunderbird instantly configured here. I just changed imap security from none to ssl/tls. No postfix configured here. -- Cheers/Saludos Carlos E. R.

Much will depend on what you do with your Linux systems, how many you have and how varied they are. How much you dabble with the hardware.
One or two linux systems running perfectly fine on my desk had no kernel modules at all. Yeah, there was a time before kernel modules... if you added in some new hardware, you had to patch and recompile the kernel. Most people complained about them at the time, but modules turned out to be a necessity... pretty much... better than a humungous megalithic kernel. I think I saw once on my phone that android uses modules, even though the precise hardware is fixed and known well ahead of time. There are a lot of advantages to modules.
