Subject: sysvinit: Should support quiet booting for splash screens

Date: Mon, 05 Sep 2005 00:39:29 +0200

Package:  sysvinit
Version:  2.86.ds1-1
Severity: wishlist
Tags:     patch

While reviewing the patches from ubuntu to the sysvinit package, I
came across a patch to quiet down init.  This is used when booting
with a splash screen, to make sure no spurious output make it to the
console.  I believe it would be useful to have this in Debian as well,
to make it possible to get a more pretty boot.  These are the relevant
changelog entries:

sysvinit (2.85-22ubuntu2) warty; urgency=low

  * changed the 'quietinit' flag to 'splash'

 -- Nathaniel McCallum <npmccallum@gentoo.org>  Fri, 20 Aug 2004 13:58:43 -0400

sysvinit (2.85-22ubuntu1) warty; urgency=low

  [...]
  * src/init.c: added a quietinit option which disabled initial boot output

 -- Nathaniel McCallum <npmccallum@gentoo.org>  Mon, 16 Aug 2004 12:15:14 -0400

And here is the patch.  Perhaps the --splash flag should be --silent
instead?

Subject: How 'bout we use INIT_VERBOSE for this?

Would it make sense to use INIT_VERBOSE to control this?

It sound like a good idea, at least.  That way the INIT_VERBOSE=no
flag would affect both the boot scripts and init itself.  Patch
welcome. :)

On the other hand the 'splash' kernel option is used to activate the
splash screens, while the 'quiet' kernel option is used to quiet down
the boot.  Perhaps it make more sense to use 'quiet' instead of
INIT_VERBOSE all over, and expect those with splash screens to use
'splash quiet' as kernel arguments if they want few messages during
boot as well as the splash screen activated?  The alternative would be
'splash quiet INIT_VERBOSE=no', as one need to tell the kernel to shut
up anyway.

I believe adding support for 'quiet' as well as INIT_VERBOSE (and
perhaps dropping INIT_VERBOSE support some time in the future), and
adding support for the 'quiet' flag in init make most sense.  Any
objections?  If not, I will go ahead with that plan.

Friendly,
