It might be a bug in the tty-force handling, but this is not a usecase for tty-force, you would be better of using systemd-ask-password I sugest you drop the StandardInput=tty-force from the service file and use this as /etc/mount_truecrypt #!/bin/sh systemd-ask-password "Please enter the password to mount your TrueCrypt volumes..." | truecrypt -t -k "" --fs-options="rw,exec,users,async,uid=root,gid=users,umask=077,noatime" --mount-options=system --protect-hidden=no /dev/sda1 /media/C > /dev/null # that is one line, but gmail will probably break it _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
