I guess it shall not be any harder to port Whonix to Devuan than porting it to original Debian.

And I need only console mode for services and daemons like anonymization router, chat, etc.

No any need for a desktop. X11. etc.

May I know, what do you think about Whonix vs OpenBSD in terms of security for a headless server without any GUI?

And why there are no any public leaks of more recent releases from grsecurity? Would not it be legal provided the kernel is GPLed?

Could not someone create a website like:
https://wpcrack.in/join-the-club-now/

It is the same idea, since Wordpress is GPLed, most its addons are GPLed too and it is legal to redistribute them for a cheaper price.

Since grsecurity is less popular than Wordpress they could set a price tag like $100-200 USD per year just to support expenses to find a new nominal LLC to purchase further updates to always a new company each time after earlier used company is banned by grsecurity, say once per 1-3 years. They could make a lag of releasing updates like a year behind of the grsec mainline, so the ban would occur only after subscription is already exhausted. It would be like a group buy campaigns.

Btw, Devuan is almost the same Debian with systemD removed from it.
Devuan even uses the same Debian binary repository with a few substitutions/replacements by its own Devuan packages just to eliminate nasty systemD.

A few more questions:

1. Does systemD track user at least by his personal machine GUID ?

2. Can systemD be operated by invisible virtualization bootkits, trojans and hardware backdoors in negative rings of the CPU just to phone home via many programs nailed hardly to systemD ?

Do you still think after that systemD allows to make an anonymization distribution?

It is important to understand, that systemD is actually much more than simply an init system:

systemD is only named "init system" just for marketing purposes to hide true (in)security hell promoted by it, IMHO actually systemD is much more like a second kernel running in parallel with general kernel and providing many new unified API for easy phoning home, remote control of many desktop program's data, etc.

More details are described here

Many spare/odd (if they would be without systemd) software processes are running, not desired ports listening, main kernel options silently changed without permission, may be something else unpredictable, it is like a living on a volcano.

If systemD would be just another init system, it would not take years from Devuan to throw it out of the distribution and replace with another true init system like OpenRC or any other like it.
