You can use all the variables used in the imaging process sourcing the
/tmp/post-install/variables.txt file, for example on top of your script
you can add the line:
. /tmp/post-install/variables.txt
Here is the list of the variables saved in variables.txt:
echo "HOSTNAME=$HOSTNAME" >> /tmp/variables.txt || shellout
echo "DOMAINNAME=$DOMAINNAME" >> /tmp/variables.txt
echo "DEVICE=$DEVICE" >> /tmp/variables.txt
echo "IPADDR=$IPADDR" >> /tmp/variables.txt
echo "NETMASK=$NETMASK" >> /tmp/variables.txt
echo "NETWORK=$NETWORK" >> /tmp/variables.txt
echo "BROADCAST=$BROADCAST" >> /tmp/variables.txt
echo "GATEWAY=$GATEWAY" >> /tmp/variables.txt
echo "GATEWAYDEV=$GATEWAYDEV" >> /tmp/variables.txt
echo "IMAGESERVER=$IMAGESERVER" >> /tmp/variables.txt
echo "IMAGENAME=$IMAGENAME" >> /tmp/variables.txt
echo "LOG_SERVER=$LOG_SERVER" >> /tmp/variables.txt
echo "LOG_SERVER_PORT=$LOG_SERVER_PORT" >> /tmp/variables.txt
echo "USELOGGER=$USELOGGER" >> /tmp/variables.txt
echo "TMPFS_STAGING=$TMPFS_STAGING" >> /tmp/variables.txt
echo "SSH=$SSH" >> /tmp/variables.txt
echo "SSHD=$SSHD" >> /tmp/variables.txt
echo "SSH_USER=$SSH_USER" >> /tmp/variables.txt
echo "SSH_DOWNLOAD_URL=$SSH_DOWNLOAD_URL" >> /tmp/variables.txt
echo "FLAMETHROWER_DIRECTORY_PORTBASE=$FLAMETHROWER_DIRECTORY_PORTBASE" >>
/tmp/variables.txt
echo "MONITOR_SERVER=$MONITOR_SERVER" >> /tmp/variables.txt
echo "MONITOR_PORT=$MONITOR_PORT" >> /tmp/variables.txt
echo "MONITOR_CONSOLE=$MONITOR_CONSOLE" >> /tmp/variables.txt
echo "BITTORRENT=$BITTORRENT" >> /tmp/variables.txt
echo "BITTORRENT_STAGING=$BITTORRENT_STAGING" >> /tmp/variables.txt
echo "BITTORRENT_POLLING_TIME=$BITTORRENT_POLLING_TIME" >> /tmp/variables.txt
echo "BITTORRENT_SEED_WAIT=$BITTORRENT_SEED_WAIT" >> /tmp/variables.txt
echo "BITTORRENT_UPLOAD_MIN=$BITTORRENT_UPLOAD_MIN" >> /tmp/variables.txt
For some post-install script examples you can look here:
http://svn.systemimager.org/listing.php?repname=systemimager&path=%2Ftrunk%2Fdoc%2Fexamples%2Fpost-install%2F&rev=0&sc=0
And post-install scripts are always downloaded from the image server at
the end of the installation process to each client.
