# this script is intended to be run as  root  by  dbootstrap  chroot-ed to the
#   target disk, at the end of the first installation stage

# this script generates scripts to be run by base-config, that fix up the
#   installed system, so that it autoinstalls our desired packages and configs
#   and does so without any questions being asked


### ------ configuration for this site

# 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

# none of these currently


# --- DEBUG_*, various debugging settings

# these can be set to "yes" by -D option, followed by name without DEBUG_
#   as this is called by dbootstrap, do this on thats hostname input line
#   such as like this:  -D PRINT_STEP -D WAIT_FIRST_REBOOT <hostname>

# set this to sleep after displaying each steps header, number is in seconds
#DEBUG_SLEEP=2

# 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

# set this so that our generated base-config scripts stay, instead of deleting
#DEBUG_LEAVE_BC_SCRIPTS=yes


# --- SYS_*, various system internal values

# none of these currently



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

# --- insert script to load our site package

# do an  apt-get install  of site package at the end
#   this allows us to do anything, including rebooting, without conflicts
