The problem is the /etc/init.d/dirmngr start skript in conjunction with package libpam-mount.
libpam-mount package postinstall script modifies the files /etc/pam.d/common-auth /etc/pam.d/common-account /etc/pam.d/common-session to include the pam_mount module by calling pam-auth-update --package These files are included at the end of pam configuration file /etc/pam.d/su for any su session. The script /etc/init.d/dirmngr contains the line output=$(su -c ". /lib/lsb/init-functions && umask 027 && start_daemon -p $PIDFILE $DAEMON --daemon --sh" - dirmngr) || return 1 to execute the daemon dirmngr as user dirmngr. This triggers the password dialog at boot time for mounting volumes stopping the boot process at the execution of the dirmngr start script. Pressing enter continues the boot process. There are (have been ?) similar issues with cron jobs using su, see Bug#401310. I would transfer the bug to the maintainer of libpam-mount. cheers ari -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
