Here;s mine, and I *am* running Devuan jessie:

hendrik@notlookedfor:~$ ps ax | grep getty
 1951 tty1     Ss+    0:00 /sbin/getty 38400 tty1
 1952 tty2     Ss+    0:00 /sbin/getty 38400 tty2
 1953 tty3     Ss+    0:00 /sbin/getty 38400 tty3
 1954 tty4     Ss+    0:00 /sbin/getty 38400 tty4
 1955 tty5     Ss+    0:00 /sbin/getty 38400 tty5
 1956 tty6     Ss+    0:00 /sbin/getty 38400 tty6
30356 pts/1    S+     0:00 grep getty
hendrik@notlookedfor:~$ 


done from a Roxterm in xcfe.

And it seems I am running getty. No problems noted here.
