It is much worse - it does not even try to open /etc/ttys :-(
I run this sequence "ktrace -di -p 1 ; kill -HUP 1 ; sleep 0.5 ; ktrace -C"
after editing /etc/ttys on both alpha and i386. Here is the result:
alpha# kdump | grep init
1 init PSIG SIGHUP caught handler=0x120002780 mask=0x9e7c9054
code=0xffffffff
1 init RET wait4 -1 errno 4 Interrupted system call
1 init CALL sigreturn(0x11ffb8c8)
1 init RET sigreturn JUSTRETURN
1 init CALL wait4(0xffffffffffffffff,0x11ffbc70,0x2,0)
i386# kdump | grep init
1 init PSIG SIGHUP caught handler=0x8049728 mask=0x9e7c9054
code=0xffffffff
1 init RET wait4 -1 errno 4 Interrupted system call
1 init CALL sigreturn(0xbfbffb70)
1 init RET sigreturn JUSTRETURN
1 init CALL open(0x8083d8b,0,0x1b6)

1 init GIO fd 0 read 7470 bytes
# type The initial terminal type for this port. For hardwired
# status Must be on or off. If on, init will run the getty program on
# If console is marked "insecure", then init will ask for the root pas\
1 init RET read 7470/0x1d2e
1 init CALL open(0x80b10f0,0x4,0)
1 init NAMI "/dev/ttyv6"
1 init RET open 2
1 init CALL close(0x2)
1 init RET close 0
1 init CALL gettimeofday(0xbfbff048,0)
1 init RET gettimeofday 0
1 init CALL sendto(0x1,0xbfbff4e0,0x48,0,0,0)
1 init GIO fd 1 wrote 72 bytes
Just for the sake of other bugbusters there are some facts:
Oddly enough, I was able to get console prompt by logging in through ssh and
running
/usr/libexec/getty Pc /dev/ttyv0 &
i.e. it works when invoked by hand, but does not get invoked automatically by
/sbin/init.
I rebiult my system on 11/15/02 and 12/02/02 -stable, but that didn't change
anything.
I track -stable on my alpha starting from 4.2-RELEASE and never seen anything
like that.
This is dmesg:
