config_eth1=( "192.168.0.4 netmask 255.255.255.0 brd 192.168.0.255" )

Those are the correct parameters, and the ones that have worked for
mnths although the format changed a few updates back.  So I think
those settings are not the problem

No

`It' being the cause of the blob of output I posted.

`Normal channels' being the init scripts like happens on bootup or when
root calls /etc/init.d/NAME start/stop/status

Those methods fail after invoking the blob of ouput.

`by hand' being:

If root looks up the appropriate flags found in /etc/conf.d/NAME, and
then starts NAME with:

# NAME $AppropriateFlags

It works like:
  # ntpd -u ntp:ntp &
ntpd starts and runs normally

  # sendmail -bd -q30m -L sm-mta
  # sendmail -Ac -q30m -L sm-cm
Sendmail starts and runs fine

No crazy output.

The ones listed above yes, but only because I ifconfiged one up.  The
normal bootup call to init scripts failed.

eth0 isn't a player in my working network for now although I do use it
occasionally.  I have 2 nics, only one in use.  It happens to be seen
as eth1 so that is what I use in /etc/conf.d/net

I'm not sure what you are talking about here.  As I stated, the bootup
init calls failed.  I've shown ntpd output as a matter of example but
only after having built the network by hand with ifconfig and route.
Not by `/etc/init.d/NAME start'.  (Again, that fails)

My sentiments too.  I wasn't even able to see where all that guff got
loaded or sourced looking thru net.lo.  I'm not a programmer by no
means but have written dozens even hundreds, I suppose, of shell scripts
and perl scripts though I've had no training on either.

However I get lost write away trying to follow how it all happens.

Here is an example from /etc/init.d/gpm below.  It is not apparent
where any of those variables get filled with a value.  I see nothing
being sourced either.  Further, what scripting language uses:
  ebegin
  eend
I've never seen it in sh ksh bash. The three most common scripting
languages (I think). What is it?


  checkconfig() {
   if [ -z "$MOUSEDEV" ] || [ -z "$MOUSE" ] ; then
  eerror "You need to setup MOUSEDEV and MOUSE in /etc/conf.d/gpm first"
  return 1
   fi
  }

  start() {
   checkconfig || return 1

   local params=""
   [ -n "$RESPONSIVENESS" ] && params="$params -r $RESPONSIVENESS"
   [ -n "$REPEAT_TYPE" ]&& params="$params -R$REPEAT_TYPE"
   [ -n "$APPEND" ] && params="$params $APPEND "

   ebegin "Starting gpm"
   start-stop-daemon --start --quiet --exec /usr/sbin/gpm \
  -- -m ${MOUSEDEV} -t ${MOUSE} ${params}
   eend ${?}

equery did show a herd of wrong mtimes.  Which I'm guessing is
probably normal but it also shows MAKEDEV missing.  So I re-emerged
it.  Following re-emerge, equery now shows:

  root # equery  check baselayout 2>&1|tee file2
  !!! /etc/rc.conf has incorrect md5sum
  !!! /etc/gentoo-release has wrong mtime (is 1135082266, should be
  1135082250)
  !!! /etc/conf.d/hostname has incorrect md5sum
  !!! /etc/modules.autoload.d/kernel-2.6 has incorrect md5sum
  !!! /etc/conf.d/clock has incorrect md5sum
  !!! /etc/conf.d/domainname has incorrect md5sum
  sys-apps/baselayout-1.12.0_pre11-r3:
   * 153 out of 159 files good

However, it didn't help the init script problem a bit.  I still see
the long list of stuff and a failure trying to start stuff with:
  /etc/init.d/NAME start

Bingo...!  It was not a symlink and was massively different.  Checking
backups from previous running system (before recent full reinstall) I
see net.eth0 and net.eth1 both symlinked to net.lo.  So renamed the
current net.eth1 and symlinked a net.eth1 to net.lo.

Starting services now works as expected.

Thank you Mr. Fish, I'd probably never have figured this out from
looking at the init process or the scripts.

Ok, are _all_ your init scripts failing here, or just ones that depend on 
network? Obviously, if you are resorting to starting your network 'by hand' 
then gentoo is not going to know internally that the network is up and 
running, and hence try to start networking for those services that depend on 
it...

Well, in your OP you can see that the ntpd init script is trying to start up 
your network (net.eth1) because ntpd depends on it to run. It cannot know 
(well, it can, but is not set up that way...) that your network is already 
running, because you started it outside of the normal channels (your term).

I do not know what to tell you at this point other than it seems your init 
scripts, or perhaps /sbin/runscript is totally borked. If you are a hands on 
sort of guy, you may want to see the init script guide:

http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2&chap=4

the second last section "writing initscripts" goes intop details of how they 
run, perhaps it can help you to walk through your scripts and figure out 
where the problem lies. If not, you might need to file a bug report, or talk 
to a gentoo dev...

A few things:

1. Run "equery check baselayout".  If it reports anything wrong in
/lib/rcscripts, re-merge it.

2. Make sure that net.eth1 is a symlink to net.lo, _not_ a copy of an
old script.

3. You can set RC_NET_STRICT_CHECKING=lo in /etc/conf.d/rc to have the
net dependancy satisified by net.lo, which will stop all other network
services from trying to start net.eth1.

Good tips Richard, thanks

Apropos, does anyone know of any good documentation about the Gentoo boot 
process and initscripts? Looking through all of these, it is difficult to 
follow what is going on, and the initscript guide I linked to before is a bit 
terse.

A major feature of every language worth knowing is the ability to
write functions.  ebegin and eend are exactly that, functions (or
procedures if you like) written in bash.  In the case of ebegin/eend,
these are defined in /etc/init.d/functions.sh.

All of the init scripts are executed by /sbin/runscript (see the first
line of gpm).  Now, this is where you would need to look at the source
for baselayout, since /sbin/runscript is a binary executable, but the
only thing that you really need to know is that /sbin/runscript runs
/sbin/runscript.sh, which is just a bash script.  It is this script
which sources functions.sh and takes care of starting (via
svc_start()) or stopping (via svc_stop()) the init script.

I'm not sure what else /sbin/runscript does, as I haven't looked at
the source for that.
