antiX-21-a1 running s6/66 with sysvinit removed.

I sense this is a breakthrough many have been waiting for… I am not an expert but I do care for clean architecture.
I am looking forward to S6 antiX, hopefully soon.
Many thanks to eric, andyprough and anti.

How crucial is it for an init file to be in /sbin/ only and not also in /usr/bin or /usr/sbin or exist as a link in /sbin/ to the /usr/bin file? I am trying to troubleshoot past experiments from memory and this is about the only thing I did differently.

This is what I have in /sbin/init.66

% cat /sbin/init.66*
#!/usr/bin/execlineb -P

/usr/bin/66-boot -b "Trying to boot Antix with 66 ...." -m

while /sbin/init is a link /sbin/init -> /lib/runit/runit-init

On grub I have one entry as a usual linux boot line the other ends at init=/sbin/init.66 this way it can boot with runit or 66.

The only intersection between the two is init halt reboot poweroff shutdown. /usr/bin/run/ and /usr/bin/s6 for the last four and /sbin/init and /sbin/init.66

Then on /usr/local/bin I have a poweroff and reboot with both having both commands /usr/bin/s6/reboot and /usr/bin/run/reboot One of them works all the time.

I saw that Antix rely on elogind. You can make a service for it easily.

Create the file /etc/66/service/elogind with:

[main]
@type = longrun
@version = 0.0.1
@description = "elogind daemon"
@user = ( root )

[start]
@execute = ( elogind )

[stop]
@execute = ( s6-rmrf ${pid_file} )

[environment]
pid_file=!/run/elogind.pid

I don’t know if its works or not on Antix. Not tested. Maybe a dependency to dbus need to be made?!?.

Note: usually distro install the services at /usr/share/66/service and sysadmin install it at /etc/66/services. The /etc/66/services take precedence over /usr/share/66/service.

So, now to enable it
# 66-enable elogind

and to start it
# 66-start elogind

Also, to configure your boot you can use

# 66-env -t boot -e mcedit boot@system

Change what you want and enable it again to apply the changes

# 66-enable -t boot -F boot@system

To reboot the machine correctly

sudo 66-shutdown -r now

To power off the machine correctly

sudo 66-shutdown -p now

Enjoy 🙂

I built 66 compatible debs for skalibs, execline, s6, s6-rc, s6-linux-utils, s6-portable-utils for buster, bullseye, testing and sid repos.
Should arrive soon.
I’ll try and build 66 debs when I get time.

At the moment they have an antix suffix. This won’t affect buster versions since Debian won’t upgrade them and they won’t get overwritten.
For sid/testing we might need to make sure we have a long-term solution to avoid any Debian upgrades overwriting our debs.

Debian has skalibs, execlines and s6 in their repos. They do not have the other debs nor any Obarun 66 debs.

@eric I tried the script on 32 bit antiX-19 – all seems well (no compile failures), but reboots to no init (Asked to Control D or give root password).
Can s6/66 work on 32 bit?

The standard method to troubleshoot is to first edit /etc/66/init.conf and turn verbosity to 4 (max) reboot and see what is in /run/66/log/0/current

Also if you can mount manually your root “mount -o remount,rw /dev/sdaxx /” and look at “66-intree -g boot” output.
At that point if you try “66-all -v4 -t boot up” it will probably show you the first thing that fails in boot.
If you see something you can fix by configuring the boot module you can edit and reboot, but since s6 is not pid1 the boot process will not complete. For getting a sulogin and having no tty12 the boot process failed too early.

/sbin/init says “66-boot -m ” right and it is chmoded +x ?

Since 66 has been in void for a long while if there was a problem with 32b or any of the architectures they support I would have heard something about it. Void rarely makes exceptions in adopting software that are architecture specific.

Hopefully Eric can throw more light into the problem.

I get this message at boot after enabling max verbosity.

I was just looking at https://skarnet.org/ where s6 is used, distributed, and one of the very best models possible of efficient server use is displayed. The server has only had one security issue EVER (in 2003) and never since; only due to network host and domain server issues has the environment had issues. the current system Kernel excluded, the amount of memory in use is: 135428 kB, very impressive indeed.

If the home of s6 is this well designed, developed and maintained, it’s a good model for a minimal, single purpose init / process scheduler. I hope we’ll get to a place where this can be our routine, every day, preferred choice init system, once we understand and implement it properly; in the meantime, runit is a viable alternative, sysvinit is “OK”, but has shortcomings and is really obsolete, so it’s worth figuring out how to install, configure, and manage this alternative. The people who put it together really understand fast, simple, single purpose stuff that’s in the true spirit of the original UNIX way, but takes advantage of lessons learned and best practice implementations. I’m looking forward to it.

the -m option on 66-boot forces the /run tmpfs to be rw on debian. On Arch it doesn’t need this.
I remember mount on debian/antix for a while wouldn’t mount if the target is not empty, unless a special swtich –non-empty was used, which I think has been deprecated on sid??? Compare the static directories of both your experiments if the /run is empty or not. I know runit creates a permanent /run/runit

Sometimes Eric is unreachable in the weekends .. so allow him some time.

Can s6/66 work on 32 bit?

It should work whatever the architecture. Also, it can be build with GCC,clang or musl. It should work on BSD and Solaris but never tested yet.

sulogin(): 84): warning : unable to wait for : 66-scandir

You seem to have a PATH definition problem here. Note: if you get a sulogin that means that the issue occur before launching any services even the main svscan responsible of the PID1. So the issue is on the 66-boot program itself. In your case the PATH of the 66-scandir cannot be found. The path is define at /etc/66/init.conf file but obviously it also depends of how the software was build. See below.

Debian has skalibs, execlines and s6 in their repos.

Apparently you use the skalibs, execline and s6 directly from debian repo which is a very bad idea because debian dev do not compile and install the skarnet softwares correctly in particular for execline. As far as i know, the execline package is completely broken. Laurent Bercot struggled a lot with debian dev about this and they do not install it correctly for obscure reason. At the last new of what i know about this, they say that execline is not a POSIX program(i never see a programs which respect the POSIX standard as many as skarnet programs) whereas systemd is it lol.

So, i advise you to build by your own the skarnet package and to define a correct path at build time. Also, you need to respect a good order to get a correct build.
the order is:
1) skalibs
2) execline
3) s6
4) s6-rc, s6-portable-utils, s6-linux-utils
5) oblibs
6) 66, 66-tools

The s6-portable-utils and s6-linux-utils is not strictly mandatory for 66 and 66-tools but its needed for the boot@-66serv service.

When you build it with the script that i posted all goes well. So yeah, debian bullshit…

Thanks eric.

However, your script works fine with 64bit but not 32 bit antiX.

I didn’t use any skarnet debs from Debian. I have repackaged them to work on antiX with 66.
(64 bit for now). Testing, but it does work.

As I said, I get the boot error mentioned after installing antiX 32 bit, then running your script.
The script completes without error.
