Force systems with kernel option "quiet" to display prompt for password
On systems that utilize TTY for password entry, if the kernel option "quiet" is set, the system would appear to freeze on a blank screen, when in fact it is waiting for password entry from the user. Since TTY is the fallback method, this has no effect on systemd or plymouth password prompting. By temporarily setting "printk" to "7", running the command, then resuming with the original "printk" state, the user can see the password prompt.
