in order to get 'savedefault' feature working. we should create “default” file on the flash, 2048 bytes long:

cat default
0

#
#
#
#
#
#
#
#
# !!!!!!! The file size is 2048 bytes. Don't change the file size !!!!!!!

we will make customization through config.txt file, that we will place in root of flash:

cat config.txt
ROOT=somepasswordhere
DEV=em0
IP=192.168.5.5/24
GW=192.168.5.1
NS=8.8.8.8

let us boot from sysresccd

from there we should make following:

mount /dev/othderdevice_with_posix_fs /mnt/custom/
mkdir -p /mnt/custom/customcd/files
cp -a /livemnt/squashfs/* /mnt/custom/customcd/files/
mount -o bind /dev/ /mnt/custom/customcd/files/dev
mount -t proc proc /mnt/custom/customcd/files/proc
chroot /mnt/custom/customcd/files/

copy from some i386 debian: -/usr/bin/expect -/usr/lib/libexpect.so.5.43.0 -/usr/lib/libtcl8.4.so.0 -/usr/share/tcltk

cat > /root/chpass
#!/usr/bin/expect -f
spawn passwd [lindex $argv 0]
set password [lindex $argv 1]
expect "password:"
send "$password\r"
expect "password:"
send "$password\r"
expect eof

cat > autorun
#!/bin/sh
PASS=`cat /livemnt/boot/config.txt|grep ROOT|cut -d= -f2`
IP=`cat /livemnt/boot/config.txt|grep IP|cut -d= -f2`
GW=`cat /livemnt/boot/config.txt|grep GW|cut -d= -f2`
NS=`cat /livemnt/boot/config.txt|grep NS|cut -d= -f2`
/sbin/ifconfig eth0 $IP up
echo nameserver $NS > /etc/resolv.conf
/root/chpass root $PASS
/sbin/route add default gw $GW

/usr/sbin/autorun

ar_nowait='y'

/etc/ssh/sshd_config

PasswordAuthentication yes

/usr/sbin/sysresccd-custom squashfs

/mnt/custom/customcd/isoroot/

let us boot from frenzy

from there we should make following:

mkdir /mnt/frenzyfs
mount -t tmpfs tmpfs /mnt/frenzyfs
cp -Rfp /Frenzy/fs/* /mnt/frenzyfs
chroot /mnt/frenzyfs/

cat > /root/autorun
#!/bin/sh
/bin/cat /Frenzy/boot/config.txt | /usr/bin/grep ROOT | /usr/bin/cut -d= -f2 | /usr/sbin/pw usermod root -h 0
/bin/echo "PermitRootLogin yes" >> /etc/ssh/sshd_config
/sbin/ifconfig `/bin/cat /Frenzy/boot/config.txt | /usr/bin/grep DEV | /usr/bin/cut -d= -f2` `/bin/cat /Frenzy/boot/config.txt | /usr/bin/grep IP | /usr/bin/cut -d= -f2`
/sbin/route add default `/bin/cat /Frenzy/boot/config.txt | /usr/bin/grep GW |/usr/bin/cut -d= -f2`
/bin/echo "nameserver `/bin/cat /Frenzy/boot/config.txt | /usr/bin/grep NS | /usr/bin/cut -d= -f2`" > /etc/resolv.conf
/etc/rc.d/sshd forcestart

chmod +x /root/autorun
echo /root/autorun >> /etc/rc.d/FRENZY
exit
mkisofs -lRNU -quiet -ldots -o frenzynew.iso frenzyfs
mkuzip -o frenzy.uzip -s 130560 frenzynew.iso 

now we get new frenzy.uzip, that we will put to /frenzy/ catalog
