Thank you for the link. Unfortunately, adding "local" to tty00 made no
difference.
The other percularity that I noticed, getty on tty00 stays in
ttyopn wait state, while other terminals where I can see login prompt,
are in ttyin state. Please see pid 11907 below:
jetway$ pgrep -lf getty
11907 /usr/libexec/getty std.9600 tty00
21180 /usr/libexec/getty std.9600 ttyC0
18041 /usr/libexec/getty std.9600 ttyC5
70940 /usr/libexec/getty std.9600 ttyC3
62965 /usr/libexec/getty std.9600 ttyC2
65765 /usr/libexec/getty std.9600 ttyC1

I wonder if getty cannot open tty00 for some reason.
