Not sure if this helps, but: have you tried dpkg -reconfigure ?

Thanks for reply
Are you mean install runit and do dpkg-reconfigure openrc or dpkg-reconfigure runit?
Is it safe, i am aware that i can broke os by this commands?

Haven't actually tried to change the init system after the install.
And after some thinking, update-alternatives sounds more like what deepforest is after.

Re: [SOLVED] Daedalus. Can i switch from openrc to runit without reinstall os?

Hi,

If it possible, how do this?

try the following

apt-get install runit-init

and then reboot the system

reboot

if plain 'reboot' doesn't work you may have to call
/usr/sbin/openrc-shutdown with appropriate options to reboot into runit

I tested sysv --> runit and going back to sysv, never tested from
openrc but it should work.

Best,
Lorenzo

@Lorenzo
Thanks man!
it seems to have worked But i not feeling any difference, only boot log looks another.
its was easy.
And to move back i must uninstall runit-init and make dpkg-reconfigure openrc or reinstall openrc?

did you installed also runit-services package?

I don't think dpkg-reconfigure has any use here; reinstall openrc + sysvinit-core should do it.
Then, to reboot from runit into openrc call

/lib/runit/runit-init 6

idk, only this apt-get install runit-init

Thanks, reinstall only openrc? Why you mentioned +sysvinit-core?

Originally openrc used to run on top of sysvinit, so you need sysvinit-core + openrc;
recently openrc got it's own init, so it can run without sysvinit.
I'm not sure what the openrc deb package does, if you install openrc without sysvinit-core
just make sure that /sbin/init points to somewhere that make sense for openrc, like
maybe

/usr/sbin/openrc-init

I never used openrc so I'm more or less guessing the above.

Re: [SOLVED] Daedalus. Can i switch from openrc to runit without reinstall os?

it looks like there is a problem with openrc postinstall script, likely a bug. As already mentioned, I know very few about openrc so I don't have an explanation. I suggest you open a bug report on openrc package linking this page

Re: [SOLVED] Daedalus. Can i switch from openrc to runit without reinstall os?

A file that is not executable on /etc/init.d/ breaks openrc installation for some reason, needs to make executable first or move to another directory

Please, next time, report bug like this! Nobody reports = nobody fixes.
It's now fixed in unstable/openrc 0.54-2

Re: [SOLVED] Daedalus. Can i switch from openrc to runit without reinstall os?

From Lorenzo's bug report:

Note that recently debhelper started to chmod -x initscripts when a package is
removed but not purged, (...)

That sounds terrible!
Is the consequence, that any sysv initscript needs to be updated to fix this behavior?
(Or: If you have such a "helper" you don't need enemies.)

Back to main topic:
Unused stuff can be removed - sorry purged - too apt purge openrc.

From Lorenzo's bug report:

    Note that recently debhelper started to chmod -x initscripts when a package is

That sounds terrible!

Why? in any case the sysv script is not usable if the binary is not installed. The chmod - x is done for heuristics, for example to be able to tell if the binary is installed and avoid to unecessary call the script if it's not (I'm talking about automatic start/restart that happens in maintainers script during package upgrades)

Is the consequence, that any sysv initscript needs to be updated to fix this behavior?
(Or: If you have such a "helper" you don't need enemies.)

Not really: the script is automatically chmod +x as soon as you reinstall the package, you don't need to worry about this.  Other tools around initscript (invoke-rc.d, runit's /lib/runit/run_sysv_scripts) were changed to cope with non executable initscripts, openrc was just lagging behind.
Note that debhelper is used at build time to help pkg maintainers to automate the build process, it affects build-time, it doesn't affects runtime.
