I'm using a read-only filesystem (squashfs). I've used the overlays file system to mount /etc directory. I can change the password using passwd command.
I've included libpam & libpwquality packages to enable the strong password policy. I see the following files are present in /etc/pam.d directory
common-account common-session-noninteractive runuser-l su-l
common-auth login screen sudo
common-password other sshd
common-session runuser su
Following is the content of `/etc/pam.d/common-password file
password requisite pam_pwquality.so retry=3 minlen=8 ucredit=-1
password [success=1 default=ignore] pam_unix.so use_authtok try_first_pass obscure sha512
password requisite pam_deny.so
password required pam_permit.so
When I try to change the password, It still allows a weak password. How to enable a strong password policy on the read-only file system with the overlay enabled?
