# this script is intended to be run as  root  at end of second install stage
#   / is root of the final system, as we are just short before login prompt


# set up and run dphys-config[1] and dphys-admin[2] as used on our site


### ------ configuration for this script

# first CONF_*  various site or subnet dependant user config variables
# then  DEBUG_* various debugging settings
# last  SYS_*   various system internal values
# some of these are overridable by hostname input line options


# --- CONF_* various site or subnet dependant user config variables

# set this to get rid of status reports, replaces -q option
#CONF_PRINT_QUIET=yes

# set this to get more status reported, replaces -v option
#CONF_PRINT_VERBOSE=yes


# --- DEBUG_*, various debugging settings

# these can be set to "yes" by -D option, followed by name without DEBUG_

# set this to sleep after displaying each steps header
#DEBUG_SLEEP=yes

# set this to output debug state info after each step
#DEBUG_PRINT_STEP=yes

# set this to output debug state info and wait after each step
#DEBUG_WAIT_STEP=yes


# --- SYS_*, various system internal values

# none of these currently



### ------ actual implementation from here on
# no user settings any more below this point

set -e


# --- get ready to work

# sanitise this place, else some commands may fail
#   must be before any commands are executed, incl config/input processing
PATH=/sbin:/bin:/usr/sbin:/usr/bin
export PATH


# --- tidy up some commands, make systematic, common infrastructure

# stuff that goes wrong, not expected by user, not in data output, use >&2
#   so also with $0 in case this script was called by an other script
# something within the system that user does not expect, give up
CMD_FATAL="echo $0: FATAL:"
# something from users input, user will correct this and continue
CMD_ERROR="echo $0: ERROR:"
# something we can continue with, but may be wrong, and user may not suspect it
CMD_WARNING="echo $0: WARNING:"
# something most likely not wrong, but tell user for the odd case it is wrong
CMD_NOTE="echo $0: NOTE:"

# normal stuff users expect, so to stdout as normal output, no $0, no marking
CMD_INFO="echo"
# stuff users asked for, so add to stdout as normal output, no $0, but mark it
CMD_DEBUG="echo DEBUG:"

# other stuff we may want to use

# --- load our sites packages

# install identd, else no access to non-free site packages and config files
#   this was once needed, for woody, but sarge already loads an pidentd
# run  yes  with  nice  , else it uses up all CPU und apt-get gets really slow
#nice yes '' | apt-get install oidentd


# - tell  apt  where to find dphys-config and dphys-admin

cat << END-APT-SOURCES >> /etc/apt/sources.list
deb http://debian.ethz.ch/pub/debian-local sarge/local main contrib non-free
END-APT-SOURCES

apt-get update


# - then configure  dphys-config  so it can find all the config files
#   http://www.phys.ethz.ch/~franklin/Projects/dphys-config/

cat << END-DHPYS-CONFIG > /etc/dphys-config
CONF_BASEURL="http://debian.ethz.ch/pub/debian-local/configs/sarge"
END-DHPYS-CONFIG

# install it, and auto-run it via its /etc/init.d script
# run  yes  with  nice  , else it uses up all CPU und apt-get gets really slow
nice yes '' | apt-get install dphys-config

# now our  apt  sources.list and  dphys-admin  config and list files are here
#   apt-get update  and  apt-cache dumpavail  and  dpkg --update-avail
#   are all done as part of running dphys-admin


# - then install of all packages our site wants, by using  dphys-admin
#   http://www.phys.ethz.ch/~franklin/Projects/dphys-admin/

# dphys-admin package is expected to:
#   a) add daily cron job to  apt-get update/upgrade, incl newer dphys-admin
#   b) add init script for the case cron job is not run due to power off
#   c) get run by its init script, fetching all packages we want
#      this allows us to do anything else, as part of packages postinst scripts
#        including even rebooting, without any conflicts or hard coded stuff
# we name all our self made packages dphys-*,
#   you are advised to use <yoursitename>-*
#   see "makesourcepackage" for generating/modifying such packages

# install it
#   it will not auto-run it via its /etc/init.d script, because apt-get active
nice yes '' | apt-get install dphys-admin

# so run manually, as if by init, we allow reboots at install time
dphys-admin init
