i8kutils, systemd and elogind files, spectre v2

[Member aquafoxyirina]

Hi! i installed antiX 19.5 some months ago, loved it although shortly after install it seemed to drag whenever i did certain things (such as open ROX fm, although only while offline). was odd but anyway, irrelevant to now, as antiX 22 x64 runit full, works perfectly

with that said, i have a few worries?
first off, my laptop seems to not start its fans, so i installed i8kutils from synaptic after looking around, it did.. nothing. but what i’m concerned about is that it installed some systemd directory/file, which i even ugh.. checked the dependancxies in synaptic and found nothing to hint would be a problem but then when randomly used “locate systemd” it found some stuff .-.
after tracing some of the places (idr anymore) and complete-removing i8kutils, the ones that it added are gone, but
even though the only packages i’ve -manually- added since install are, in total:
(after uninstalling, i reinstalled) kernel 4.9.0-326 via package manager
installed xinput 1.6.3-1 via synaptic (in order to auto disable Dell laptop touchpad and touchscreen and webcam, very useful)
installed chinese, japanese, korean, russian, and ukrainian fonts via package manager
installed GIMP-full via package manager
installed lynx and lynx-common via synaptic
then installed, then removed, i8kutils
(all on running IceWM)

so what i’m worried about is if i somehow pulled in systemd/elogind/such things!

“locate systemd” gives:
/etc/apt/preferences.d/00systemd
/usr/bin/deb-systemd-helper
/usr/bin/deb-systemd-invoke
/usr/share/mime/text/x-systemd-unit.xml
/var/lib/apt/lists/la.mxrepo.com_antix_bullseye_dists_bullseye_nosystemd_binary-amd64_Packages
/var/lib/apt/lists/la.mxrepo.com_antix_bullseye_dists_bullseye_nosystemd_binary-i386_Packages

(i realise the lists are safe LOL, but putting for reference/completeness)

and “locate elogind” gives:

/usr/lib/elogind
/usr/lib/elogind/system-sleep
/usr/lib/elogind/system-sleep/49-tlp-sleep

(tlp in synaptic mentions these, but tlp is also involved with i8kutils and i didn’t check this until after…)

locate libelogind and libelogind0 give nothing, not using any desktop environment as it’s warned could bring in (though really i don’t like DE anyway so)

the other big issue i’m worrying about is that in boot, it gives me a warning:
[ 0.092641] Spectre V2 : WARNING: Unprivileged eBPF is enabled with eIBRS on, data leaks possible via Spectre v2 BHB attacks!

i don’t really have any clue here, is there a way to restrict it to privileged only, is that undesirable, or? also: for info, i enabled the like.. disc encryption option when installing antiX 22, the spectre message appears right before it asks encyrption password on boot
i also see something mentions a warning after successfully passing this and just before slimski login page, but it zooms by way too fast that i can’t read it

Usually I would say that this happens because you are using so little CPU power that the fans are not needed to cool down your CPU- but it that happens when you are performing tasks that make intensive use of the CPU, then you have reasons to be worried…

Yeah, I never tried to install systemd (not on porpoise) and that command still presented me with lots of hits…

I’m not running antiX 22, but I think installing some apps may install elongind dependencies…

Hi, you cannot install ‘systemd’ in antiX by design.
The file ‘/etc/apt/preferences.d/00systemd’ is to prevent it from ever installing by assigning priority ‘-1’ to this package.
Search for: “apt pinning” and see e.g. https://gist.github.com/JPvRiel/8ae81e21ce6397a0502fedddca068507

I haven’t installed antiX-22 yet but based on the discussion about LXDE inlib antiX-22, I believe that pulling in ‘[lib]elogind’ is possible.
Of course, one can add a new file similar to the aforementioned ’00systemd’ to apt preferences to prevent that as well.

BTW, to find out if a package of known name is installed, I prefer use ‘apt-cache policy <package-name>’ instead of ‘locate’.
The ‘<package-name>’ can contain a wildcard, e.g. using ‘syste*d’ did find more results than exact name ‘systemd’.

Friends, you may do whatever you want with your own systems. However to alter the design of antiX automatically leaves you on your own. Either reinstall it, go through considerable effort to figure out what has changed or install a different system.

We’re decidedly different, we choose to have a lean systemd free architecture and that’s the choice of the founder and owner of antiX.

[ 0.092641] Spectre V2 : WARNING: Unprivileged eBPF is enabled with eIBRS on, data leaks possible via Spectre v2 BHB attacks!

I also get this message on start up. It doesnt sound very reassuring.

According to various reports, it is nothing to worry about.
It is a warning that got patched in later kernels (5.17 and later).
ie there is no vulnerability to be worried about.

Philosophers have interpreted the world in many ways; the point is to change it.

antiX with runit - leaner and meaner.
