Need help with Getty-tty5 and runit setup.

ReaperX7 · 02-26-2014, 04:39 PM

I'm trying out the alternative init system runit-2.1.1 from here:

http://slackbuilds.org/repository/14.1/system/runit/

So far I've proceeded through the setup of directories and symlinks as described in the documentation to the part of the switch over where it says to setup launching a getty on tty5, but therein lies a critical problem...

I've hit Ctrl+Alt+F5 on rebooting with init=/sbin/runit-init and no getty has appeared as was supposed it and the system has loaded most of the system in single user mode more or less from what I can observe.

The level 1 script I have had to be edited as follows:

Code:

#!/bin/sh
# system one time tasks

PATH=/command:/sbin:/bin:/usr/sbin:/usr/bin

/etc/rc.d/rc.S
#/etc/init.d/rmnologin

touch /etc/runit/stopit
chmod 0 /etc/runit/stopit

as Slackware doesn't have a rmnologin or rc.rmnologin script anywhere in the system, and I did use whereis to try and search for it, but to no avail.

My question is did I set up the getty for tty5 incorrectly, did I miss something in the documentation (doesn't seem like it), is the runlevel script wrong?

I'm also going to post my runlevel 2 and 3 scripts just to be safe:

Runlevel 2

Code:

#!/bin/sh

PATH=/command:/usr/local/bin:/usr/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/X11R6/bin

runsvchdir default >/dev/null

exec env - PATH=$PATH \
runsvdir -P /service 'log: ...........................................................................................................................................................................................................................................................................................................................................................................................................'

Runlevel 3

Code:

#!/bin/sh
exec 2>&1

PATH=/command:/sbin:/bin:/usr/sbin:/usr/bin

LAST=0
test -x /etc/runit/reboot && LAST=6

echo 'Waiting for services to stop...'
sv -w196 force-stop /service/*
sv exit /service/*

echo 'Shutdown...'
/etc/init.d/rc $LAST

Other than possibly editing the obvious links to sysv /etc/init.d/ directory paths and other commands, what else do I need to do?

Well, I didn't try it (and won't :-), but this doc says:

Quote:

Step 3: The getties
At least one getty must run in stage 2 so that you are able to login. Choose a free tty, say tty5, where sysvinit is not running any getty (edit /etc/inittab and kill -HUP 1 if needed), and tell runsvdir about the getty-5 service:

# mkdir -p /service
# ln -s /etc/sv/getty-5 /service/

But in genuine Slackware /etc/inittab does run a getty on tty5.

Just comment out this line:
c5:12345:respawn:/sbin/agetty 38400 tty5 linux
if you want to free tty5.

Thanks Didier. I'll re-check it later when I get home, or tomorrow when I have time. If anyone else has any other suggestions for stuff I should worry about later on, please let me know.

Are you using agetty? I've just tried it on a VM (14.1 64-bit), and it doesn't seem to work with runit. getty from getty-ps works.

This is what I used for /etc/sv/getty-5/run

Code:

#!/bin/sh
exec /sbin/getty tty5

Thank turtleli, I just noticed that, but there wasn't too much documentation on which getty package was the recommended. I'll retune it tomorrow and try again.

My hope is to possibly get a working script set drafted soon (possibly even put up on SBo) but getting Runit working in administrative mode is the first order of business.

I would like to get a how-to made once this is all said and done. The Runit package on SBO doesn't really have too many extra hints to doing an init swap-out.
