I want to change passwd of root of nspawn container, as I am creating container via ansible just after I created rootfs, as at very first it doesn't have any root password.
is it a good idea to change passwd by using replace module to replace root line in /etc/shadow file ?
is there any other way too to update the password non-interactively ?
I have tried :
echo user:pass | /usr/sbin/chpasswd
but echo is not working, a I am getting execv() failed: No such file or directory

passwd works for this case. It has an option --stdin. Do not use echo my-secret-password | passwd --stdin, because echo my-secret-password may become visible if someone runs ps, or maybe even in a log file if you are unlucky.
#!/bin/sh
PASSWORD=...
passwd root --stdin <<EOF
$PASSWORD
EOF

Thanks for the answer, but this is working fine in host, even the echo one which I mentioned above is running fine too in host, but failing in nspawn container
