Supervisor can't start DNS, Audio and Multicast

[Glesa-Gilles]

Describe the issue you are experiencing

Since a quite usual reboot 2 days ago I ran into non working integration (MQTT show entities as unavailable while I see values in the topics, lot of integration requiring web access no more loading).
I dig into the logs and was surprised that both DNS, Audio and Multicast are reporting "exec /init: no such file or directory" in their logs since the related reboot.
I made this reboot due to electric issue, I haven't performed any configuration change on my instance except applying updates when proposed.

I'm running homeassistant from the "green" box.

I tried some cli commandes to get more info:

• ha dns stats reports Error: Container hassio_dns is not running
• so ha dns restart reports in the supervisor log

Any idea on how I could ensure I can restart all the system containers without reinstalling everything ?
Any idea about what could be the root cause or suggestions about investigation I can make ?
As all my heating is managed by this, it's quite problematic.

What type of installation are you running?

Home Assistant OS

Which operating system are you running on?

Steps to reproduce the issue

That's the main issue, it happened without real change

Anything in the Supervisor logs that might be useful for us?

Seems linked to these but not sure:
https://community.home-assistant.io/t/dns-issue-on-ha-if-im-right-but-why/813556/26
https://community.home-assistant.io/t/factory-reset-ha-green-solution/960473

I finally had to reset the HA Green to factory setting and import my backup.
I don't have a clue about what is the root cause or what could be a more "elegant" way of rebuilding the "potentially corrupted" DNS/Audio/mDNS containers, if anyone have an idea I would be happy to try next time it occurs.
As no real diagnostic is done I expect this to happen again randomly.
