Debian Buster terminal autologin
Note: This may be or may be not related to your problem, but the problem I explain here will lead to the same error messages you have shown due to a missing symlink.
I am not an expert, but in Debian 10 (Buster) the default init system is systemd
which means /sbin/init
(/usr/sbin/init
) will link to systemd
.
Unfortunately there is a bug I noticed when running multiple KVM guests which causes that the symlink /sbin/init
which links to /lib/systemd/systemd
is removed. I don't know the reason for that, however, I suspect that org.freedesktop.systemd1
(I absolutely don't know what that is) could be the reason.
Correct Symlink
The correct output would be:
root@vpstest:~# ls -la /sbin/init
lrwxrwxrwx 1 root root 20 Jan 29 19:07 /sbin/init -> /lib/systemd/systemd
Missing Symlink
If it shows that, there may be something wrong:
root@vps1:~# ls -la /sbin/init
-rwxr-xr-x 1 root root 53016 Feb 14 2019 /sbin/init
Fix
To fix that, I just remove that file and rebuild the symbolic link:
rm /sbin/init && ln -s /lib/systemd/systemd /sbin/init
When you're using virsh you need to destroy and then start the guest:
virsh destroy vps1 && virsh start vps1

I'm repacking a Debian Buster Live ISO. I first unpack the
filesystem.squashfs
, thenchroot
in the unsquashed system, make my changes.I want my ISO to autologin (terminal). I've followed this techniques, but I failed because I get the error:
System has not been booted with systemd as init system (PID 1). Can't operate. Failed to connect to bus: Host is down
So I can't use
systemctl
, which throws this error.The answers I've found here to bypass the error say to use
service
instead ofsystemctl
, which doesn't apply in my case.
Is poosible to autologin using another technique?
Is possible to get
systemctl
functioning inside achroot
, so I can apply above technique?
Tentative answer:
I created the file
[email protected]
under/lib/systemd/system
and made a sysmlink in/etc/systemd/system/multi-user.target.wants/
. The contents of the file.[Service] ExecStart= ExecStart=-/sbin/agetty --autologin root --noclear %I 38400 linux
This got me into autologin. I'll wait for insight before answer my own question.

JdeBP over 4 yearsDoes this answer your question? How do you configure autologin in Debian Jessie?

schrodingerscatcuriosity over 4 years@JdeBP The problem in my case is that I can't run
systemctl
, wich gives me the error I posted in the question. -
John Hawthorne over 4 yearsHow are you repacking the live OS? It doesn't sound like you are using this, but the live-build package is for building custom live images. It's easy enough to use and you don't have to unpack anything.
