I use systemd-tool mainly to unlock the LUKS encrypted volumes of my remote server by means of tinysshd. My setup exhibits the annoying behaviour of a 12sec delay before the passphrase prompt appears. For some reason await_console_stable always detects changes in the console - even in a pseudo tty (remember tinysshd) where definitely no boot messages interfer. I was unable to track down the root cause of this faulty behaviour. The outputs of tail -c 256 /dev/vcs (as used in read_console_tail) are identical whenever I run this command by hand. Seams to be a heisenbug.
Anyway: IMHO await_console_stable doesn't make any sense with pseudo TTYs. So I simply disabled this function when command tty returns something matching /dev/pts/*. With this fix whenever I log into my freshly booted machine with SSH I get my passphrase immediately.
