Summary:                    (init) inittab handling broken in revision 17937
Description: 
Since revision 17937 not all items in the inittab are executed.

My inittab file:

::sysinit:/etc/init.d/rcS
::wait:/etc/init.d/rc 2

tty1::respawn:/sbin/getty 38400 tty1
tty2::respawn:/sbin/getty 38400 tty2

::restart:/sbin/init

::shutdown:/etc/init.d/rc 0


The "wait" (rc 2) and "shutdown" (rc 0) scripts are not executed after rev
17937, also if I replace the "wait" with a second "sysinit" this line is
not executed. Running rc 0 or rc 2 by hand or using a busybox before rev
17937 works fine.

Libc: uClibc-0.9.28
gcc: gcc-3.3.3

The problem seems to be a bit different. No init startup/shutdown output is
shown on the console anymore and some daemons won't start up on boot time
with this revision (maybe they need a controlling tty?). Some examples of
daemons that won't start on init: dnsmasq and ulogd

I'm seeing a similar issue with Busybox 1.7.2

Inittab does not reliably execute the following lines:

# Startup the system
null::sysinit:/bin/mount -t proc proc /proc
null::sysinit:/bin/mount -n -o remount,rw /
null::sysinit:/bin/mount -a
null::sysinit:/sbin/ifconfig lo 127.0.0.1 up
null::sysinit:/sbin/route add -net 127.0.0.0 netmask 255.0.0.0 lo
#run the pre init script
::sysinit:/bin/echo "running rc.pre-init"
::sysinit:/etc/init.d/rc.pre-init
::sysinit:/bin/echo "rc.pre-init done"
null::sysinit:/bin/hostname -F /etc/hostname
# now run any rc scripts
::sysinit:/bin/echo "running rcS"
::sysinit:/etc/init.d/rcS

Sometimes rc_pre-init runs, sometimes it doesn't.
Sometimes rcS runs, sometimes it doesn't.

Results vary between boot ups.

Programs which need controlling tty can be started like this:

::sysinit:/bin/cttyhack <program> <params>

> Sometimes rc_pre-init runs, sometimes it doesn't.
> Sometimes rcS runs, sometimes it doesn't.

What does it print? Does it help when you add /bin/cttyhack as shown
above?

Try disabling FEATURE_INIT_SYSLOG and watching init messages on VT 5.
(Strange method of sending messages, if you ask me).
