splash_util, being dynamically linked, won't work from an initramfs unless you're willing to include glibc, libpng, freetype2 etc with it. And that _will_ make the image huge :) Best regards.
hello,

You are right, but that doesn't matter  if you are using initramfs into the kernel file instead initrd (My kernel is just 5Mo huge). With the switch_root command you will have the full memory back again :). In fact, i didn't implement splash_util into the cpio file because of some freezes and lack of time :)

Anyway, i tried to compile splashutils-1.4.2 without success. It seems we are now unable to use it without the kernel patch which also i cannot install :(

Have you dropped the 100% gensplash userspace solution ? why ? :cry:

No, I haven't. Are you sure your klibc is built against a clean tree
that hasn't been patched with splash? 

You might want to check for the presence of the following file:

/usr/lib/klibc/include/linux/console_splash.h

If it's not there, you should get a warning about missing fbsplash
when merging splashutils. If you get the warning and it still fails to
compile, then I have a bug to fix :)

Best regards.

Fbsplash doesn't work as a module, it can only be used when fbcon is
compiled into the kernel.

If you want to have splash_helper's functionality _inside_ the kernel,
just use bootsplash. Putting userspace stuff, like JPEG and PNG
decoders, where it belongs (i.e. userspace) was the most fundamental 
design idea behind splashutils :)

Perhaps, but putting it inside an initramfs isn't a very good idea. It
would be better to aim for a very fast boot during the early-userspace
stage and to let the splash daemon be started the normal way (i.e. by
the Gentoo baselayout scripts).

Right, that's a problem with how anims are handled in 1.3.1 and it's
indeed fixed in 1.4.2.

I'll keep that in mind and maybe implement it when I have some more free
time.

Have you had a chance to try splashutils 1.4.2 with baselayout-2*? If
so, did it fix the missing-splash-screen problem?

Best regards.

Re: I'm not able to get the vertical bar with gensplash after issuing alt+f1 key during the earlier boot stage


Hello Spock,

Sorry for the late reply. It becomes an habit :) Anyway, i was busy to
get the early boot script work with splashutils daemon last week end. I
didn't even have too much time to decipher all the possibilities your
program offers. I certainly missed some features it would offer. Also, i
still encountered many difficulties with the daemon and i would like to
discuss about it with you and perhaps even convince you to bring some
modifications to it.

The idea is: - to get a usable environment, even with music (debugging
could be quite long ;), when you are not able to boot the system anymore
(vi, gpm, alias, lvm, mdsetup, vgscan, fsck etc),- to stay full modular
and also - to support any filesystem you want (reiserfs, etc.) before
you even know anything about your drives. Most everything, i still want
to get the system as simple as possible.

In fact, after customising a configuration file that handles icon and
animation pictures, i begin to get in trouble :)

I need the helper after the daemon has stopped (it has displayed a lot
of nice icons before) and when the script switched to the real root file
system. It hides the console when the script will proceed.

As the helper didn't understand services, all the icons are displayed on
the screen and are scrambled with vertical stripes. To get rid of that,
i need to delete all the icon/anim lines in the configuration file. That
is a pity. Indeed, it would certainly be good to add some more options
to the helper to avoid the script to have to modify the configuration
file every time it calls the helper. Indeed, the file cannot contain
pre-declaration of icon/anim directives. Busybox doesn't understand "sed
-i", so you need a temporary file and your script becomes... more
complicated.

About animations, they are looping quite strangely when any other icons
are declared in the configuration file. They are displayed too, whatever
the services they belong to are.

Anyway, i'm quite satisfied with the result. Ash is strong enough to
handle the job well. The script stays readable :)

I tried to intercept the keyboard keys directly from the script as
gentoo baselayout v1 does (interactive mode) but without much success.
When the silent mode is called from the helper or the daemon, the script
doesn't react to the key i pressed, except the Alt-F1 key managed by the
kernel or the F2 key when called from the daemon.  I tried stty in raw
mode too. I will confess, i didn't remember how ttys are handled by the
kernel and who cares ... until you really need them, especially when you
try to call extra keys like F3 or something similar :)

IMHO, letting the script directly handle the keyboard would help to
simplify all the thing, but how ?

Also, you asked me if i have tried baselayout version 2 with splashutils.

In fact, i will certainly never be able to switch to version 2. It is
written mostly in C (and that is a bad idea ;). It isn't flexible enough
whereas a rc bash will always be. In my case, it won't call the critical
services the kernel will need early enough or even in the right order to
help a mdp/lvm boot disk to mount :(.

Believe me, only scripts are able to save the world !

I'm not sure what you mean here, can you elaborate?

Are you worried that your kernel might be broken so much that it won't 
be able to execute ELF executables? If so, you'd also be screwed on the 
script approach, because busybox/ash is also written in C.
