Hey there.

I'm trying to configure slitaz to display as small amounts of messages when booting as possible.

Up until now, I've set as default US keyboard, so I don't have to choose it. I've also added the "quiet splash" option when booting.

Now I am left with the ISOLINUX 3.82 [...] message, then silence for about 2 seconds (which is desired), but the slitaz seems to kick in (or is it still GRUB?) and it starts to tell me what's OK and what was turned on (messages ending with yellow [OK]).

Then, command line opens up, and it says "Welcome to your box" + some additional slitaz text.

Now, if possible, could I make it not say ANYTHING at all, make the login automatic (so you login as root with password root), and the first thing to display would be the command to execute?

It is worth mentioning that I must configure the slitaz .iso files itself. (I am running on RAM only)

Open /etc/init.d/{rcS,bootopts.sh,system.sh} in a text editor.
Put # in front of echo and status lines you don't want to see.
Depending on cmdline options and daemons installed you may have to edit other start scripts in /etc/init.d
Recursively grep / filesystem for the source of hard to find messages to locate the script that echos.

This is a bit of a necro post, but since I had to get back to it, the problem remains.

I edited rcS, bootopts.sh and system.sh, removed all unnecessary echos, but yet I see lots of such messages appear during boot. (pcireport, then trying to load rootfs image, and more)

Is there really no other way to just turn off all echo'ing during boot? If not, have you got any idea what other files could I possibly modify?

Add quiet to bootloader kernel command line.

Nearly everything's gone! Nearly :P

After a while of silence, I get the following messages:
Switching / to tmpfs [Skipped]
[Ok]
[Ok]
[Ok]
[Ok]
[Ok]
[Ok]
[Ok]
Detecting PCI devices Kernel modules...
* loaded module: intel_agp
* loaded module: sns_ens1371
Detecting USB devices Kernel modules...

Then something about udhcp.

I suppose the last one I can modify in some shell script (something related to network, I'd guess), but I'm not so sure about the PCI devices thingies.

Also, is it possible to customize the first-ever message: "ISOLINUX 4.05 2011-12-09 ETCD Copyright (C) ..."?

This could prevent hardware drivers from auto loading disabling the computer.
If so add the driver name to /etc/rcS.conf LOAD_MODULES=
Comment this section in /etc/init.d/rcS
```

# kernel modules only at first boot or in LiveCD mode.
if [ ! -s /var/lib/detected-modules ]; then
tazhw init
fi
```
If udhcpc message is
"Starting udhcpc client on: $INTERFACE..."
Comment this out of /etc/init.d/network.sh
echo "Starting udhcpc client on: $INTERFACE..."

Syslinux message would require hacking the source code and recompiling.

Hm, after a few seconds of silence (after booting), I'm getting something like that:

(much white space) [Status]
(much white space)

(much white space)
udhcpc (v1.18.4) started

Sending discover..
Sending select for 192.168.60.132...

Any idea where is that coming from?

At the moment I simply need to somehow silence busybox. I think it's all that's left. How do I do it, though? :/
