Package: runit-init

Dear Maintainer,
Hi!
I have Devuan Excalibur with Incus (forked from LXD) managed LXC
containers. reportbug said the package is unforked and thus I agreed
to send to Debian BTS instead.
All but one of them are Alpine Linux. In there I installed dhcpcd for
dual stack DHCP from Incus managed dnsmasq.
I am currently configuring myself a Devuan template starting from
incus launch images:devuan/daedalus zdevuan
I installed runit-init and socklog-run in there.
The containers comes up but dhcpcd is not running.
It should have been started by /etc/init.d/networking due to
/etc/network/interfaces:
auto eth0
iface eth0 inet dhcp
And indeed it is:
root@zdevuan:~# /etc/init.d/networking start
Configuring network interfaces...dhcpcd-9.4.1 starting
[…]
However even with:
root@zdevuan:~# cat /etc/boot.d/network
#!/usr/bin/env sh
/etc/init.d/networking start
it does not work.
I looked up how runit stage 2 runs init scripts. It does so by:
root@zdevuan:/etc# grep -r "rc2.d"
runit/2: /lib/runit/async-timeout /lib/runit/run_sysv_scripts
'/etc/rc2.d'
So I ran
/lib/runit/async-timeout /lib/runit/run_sysv_scripts '/etc/rc2.d'
manually and indeed it picks up /etc/boot.d/network:
root@zdevuan:~# /lib/runit/async-timeout /lib/runit/run_sysv_scripts
'/etc/rc2.d'
dmesg: read kernel buffer failed: Operation not permitted
Not running dhcpcd because /etc/network/interfaces ... failed!
defines some interfaces that will use a DHCP client ... failed!
Configuring network interfaces...dhcpcd-9.4.1 starting
[…]
That last line is from /etc/boot.d/network.
Thus I tried to find out whether /etc/runit/2 actually runs those scripts
on boot:
38 echo "$runsv_dir" 2>&1 >> /tmp/rc2.log
39 ls -l /etc/runit/no.emulate.sysv 2>&1 >>/tmp/rc2.log
40 if [ "$runsv_dir" != solo ] && [ ! -e /etc/runit/no.emulate.sysv ];
then
41 echo "run rc2.d scripts…" 2>&1 >>/tmp/rc2.log
42 /lib/runit/async-timeout /lib/runit/run_sysv_scripts
'/etc/rc2.d' 2>&1 >>/tmp/rc2.log
43 fi
This gives me:
root@zdevuan:~# cat /tmp/rc2.log
default
run rc2.d scripts…
Not running dhcpcd because /etc/network/interfaces ... failed!
defines some interfaces that will use a DHCP client ... failed!
Configuring network interfaces...failed.
So indeed stage 2 runs the scripts. But it cannot configure the network
interface at this time. However running
/lib/runit/async-timeout /lib/runit/run_sysv_scripts '/etc/rc2.d'
later just works okay as shown above.
Also putting "/etc/init.d/networking restart" inside
"/etc/boot.d/network" does not work:
Running /etc/init.d/networking restart is deprecated because it may not
re-enable some interfaces ... (warning).
Reconfiguring network interfaces...failed.
Not even putting
echo "ifdown eth0:"
ifdown eth0
echo "ifup eth0:"
ifup eth0
in there does work:
root@zdevuan:~# cat /tmp/rc2.log
default
run rc2.d scripts…
Not running dhcpcd because /etc/network/interfaces ... failed!
defines some interfaces that will use a DHCP client ... failed!
ifdown eth0:
ifup eth0:
No output from "ifup eth0" which does not seem right.
However "ifdown eth0" and "ifup eth0" just works fine after booting. But
even if I insert a "sleep 10" before those, it still does not work.
I also looked for how rcS.d scripts are executed by Runit stage 0:
root@zdevuan:/etc# grep -r "rcS.d"
[…]
runit/1: for script in /etc/rcS.d/S* ; do
In there I added for debugging:
11 for script in /etc/rcS.d/S* ; do
12 path=$(realpath "$script")
13 name=${path##*/}
14 [ -e "/etc/runit/no.emulate.sysv.d/$name" ] && continue
[…]
19 echo "run $script" >>/tmp/rcS.log
20 "$script" start --force-sysv 2>&1 >>/tmp/rcS.log
21 done
And indeed stage1 runs the scripts. But configuring network interfaces
fails there as well:
root@zdevuan:~# cat /tmp/rcS.log
run /etc/rcS.d/S08mountall.sh
Mounting local filesystems...done.
Activating swapfile swap, if any...done.
run /etc/rcS.d/S09mountall-bootclean.sh
Cleaning up temporary files....
run /etc/rcS.d/S10brightness
run /etc/rcS.d/S10procps
Starting Setting kernel variables: sysctl is already running.
run /etc/rcS.d/S10stop-bootlogd-single
run /etc/rcS.d/S10urandom
run /etc/rcS.d/S11networking
Configuring network interfaces...failed.
run /etc/rcS.d/S12mountnfs.sh
run /etc/rcS.d/S13mountnfs-bootclean.sh
Cleaning up temporary files....
run /etc/rcS.d/S14bootmisc.sh
However as bootlogd is not being started and would not work inside
an LXC container anyway, I am not sure I can see any logging:
root@zdevuan:~# /etc/init.d/bootlogd start
Starting boot logger: bootlogdbootlogd: ioctl(/dev/pts/2, TIOCCONS): Operation
not permitted
Any idea how to find the cause of what is happening here?
Best,
