Hello all,
I have been advised to use systemd-nspawn and machinectl in place of chroot to run services from a cloned, working remote host.
Another interresting behavior is when I start it with the UID shifting feature -U
$ systemd-nspawn -bUM clone-messagerie
I could wait forever (well, more than 5 minutes)
and no login prompt would appear.
If I remove the -U flag,
the container boots fine and the login prompt is shown after around 30 seconds,
mainly because it is failing to start mysqld
(which has a hardcoded 30 seconds sleep value in its mysqld_safe shell script)
