Onderwerp: Re: [DNG] Mass bug filing: use and misuse of dbus-launch (dbus-x11)
Hi!

I read this great Devuan ML whenever I have time, and am still so
excited to be using Devuan some day, but am slow to learn things (am
almost 60 and started less then 20 ys ago, before that I was not a
computer user at all... and I work slow like a turtle.)

The original that I was able to find:

[ same title as this Steve Litt's message I'm replying to ]
https://lists.debian.org/debian-devel/2016/09/msg00056.html
(and a backup for future reference, just in case:
http://osdir.com/ml/debian-devel/2016-09/msg00056.html )

I'd need more time to understand the full details of this message
(reported in its entirety below, I believe):

I like the statement above so much. That's what I felt it was pretty
soon, really more like felt than understood, and I was so right... Well:
I vaguely but impressively understood, as user.

"dbus is" (probably was part of the plan, and not just become all of a
sudden) "now just a pretty entry point to systemd."

That's what I was, of course not so explicitely and not in such learned
words ;-) but that's what I was saying back when I wrote:

Uninstalling dbus and *kits (to Unfacilitate Remote Seats)
https://forums.gentoo.org/viewtopic-t-992146.html

and Isaac Dunham put it more clearly than I would know:

https://lists.dyne.org/lurker/message/20150724.032546.cdebd81f.en.html

"The OP" (me, Miroslav Rovis) "has repeatedly stated that systemd,
pulse, and dbus are all backdoors for remote exploits, and provided
notes on removing them with the aid of Thorsten's repositories and
hardening a system with grsec; these notes have been useful to some,
despite the OP not being fluent in English."

See the thread:
https://lists.dyne.org/lurker/thread/20150727.104841.34107d9e.en.html#20150727.104841.34107d9e
Steve wrote there too...

So, just let's make people aware that:

=====================================================================
"systemd, pulse, and dbus are all backdoors for remote exploits"
            ( in my strong opinion )
=====================================================================


Of course, as soon as I'm able to (I only install in Air-Gapped, no way
would I install straight from the Internet and trust that the system is
clean... )

[Of course, as soon as I'm able to], I surely will go for (or from):

https://git.devuan.org/dev1fanboy/Upgrade-Install-Devuan/wikis/Upgrade-to-Devuan-and-minimalism

because there's "Removing dbus" there ;-)
)

And maybe one note allow me to add:

The great OpenRC which Gentoo folks offer to the world boasts no
dependency on Dbus:

https://wiki.gentoo.org/wiki/Comparison_of_init_systems

and I see the plan is to go the OpenRC way in Devuan...

I hope you guys won't all grow gray long beards before I finally install
Devuan ;-)
