Maybe I worry too much, but given the easiness an expert can own your system today, because of the treason, yes, allowing such hooks into the kernel is Linus' own treason on the users of his kernel...
What did he think? That no one would read out what those software architecture that goes by the name linux capabilities is for, apart from what it is on the surface?
I thank whom you name (us Christians, and Muslims and other religions, thank God), but if you want me to, I thank the god GNU, if you want, for the fact that such honesty is there in such genius, Brad Spender Spengler, which is maybe the sole match to Linus Torvalds in among the known security experts, for us the general GNU/Linux population, to have that article available for reading.
To me that is one of the most important revelations in computing ever!
Go read it again, whoever is reading this post. There's so much in there!
And couple that with the fact that dbus, which is part of poetteringware architecture, uses ssh-agent for some arcane purposes... Which purposes? ssh is for encryption, and I am allowed to encrypt things in my computer... Only me.
But dbus, consolekit (which may have gone away, replaced with same functionality in systemd itself, whatever)... and such stuff... Uh-uh! I don't like them encrypting, because such programs are done for multiple "seats" (that is their terminology). That is, not just the user sitting at his computer, but other "seats" as well!
I'm scared. Scared for losing my privacy in my own computer.
This is not off topic. Systemd is there for such purposes as I claim above. The plutocracy few people who started those false GNU projects, that can go by the name poetteringware just fine, the unknown to the public small bunch supported by a multitude who care solely/predominantly/sufficiently for their interests more than for the common interest (which, the common good, the GNU was all about since its inception, the freedom and the common good)...
Those tiny fraction of the one percent kind of people who got these projects going, through corporate capital, and with that huge support they are getting from people who care for common good from too little to up to being able to outright easily sell their neighbor, let alone common good!...
...They are taking away all the freedom and common good away from our GNU/Linuces...
