Making a custom Devil Linux 1.6.3 boot CD for a network gateway
---------------------------------------------------------------
Boot Devil Linux 1.6.3 CD made from downloaded .iso on machine with spare
harddrive. I used an old 4G, freshly formatted with ext3.
Log in as root, run
 setup
 save-config -d /dev/fd0
 save-config -d /dev/hda1
The result is that the configuration that works is in /etc-mods.tar.bz2 on
floppy and harddrive.  I am about to make a CD that boots to that
configuration. I'll then disconnect the harddrive and have a read-only,
unmodifiable gateway.

The booted system is mostly read-only, but /shm can be modified.
Create mount points
 mkdir /shm/FLOP
 mkdir /shm/4G
 mkdir /shm/ISO
 mkdir /shm/CDRW
 mkdir /shm/8G
Find USB flash drive
 ls /dev/disk/by-label     (my flash drive's label is 8G-KGHN)
Mount devices for use
 mount /dev/hdc /shm/CDRW  (the Devil Linux CD)
 mount /dev/fd0 /shm/FLOP  (the floppy, disk must be seated when mounting,
optional)
 mount /dev/hda1 /shm/4G   (my 4G harddrive, ext3 format OK, not vfat)
/shm/ISO will be used by script, no manual mount needed.
 mount /dev/disk/by-label/8G-KGHN /shm/8G  (USB flash drive, optional)

Set up harddrive with files to be written to the new .iso
 mkdir /shm/4G/NEW
 mkdir /shm/4G/NEW/config  (where configuration file is on CD)
 mkdir /shm/4G/NEW/boot    (wanted by script)
 mkdir /shm/4G/NEW/doc     (wanted by script)
Don't add /shm/4G/TEMP because the script wants to create it, and
complains if it's there already.
 cp /shm/4g/etc-mods.tar.bz2 /shm/4G/NEW/config
 cp /shm/4g/etc-mods.tar.bz2 /shm/4G/NEW  (redundant copy in root of CD,
may be optional)

Make .iso creation environment ready
Copy the script to the writable harddisk for editing
 cp /config/scripts/custom-cd /shm/4G

custom-cd script uses mkzftree utility. It is not on the CD. The source
files for it are on the Devil Linux website, so I copied
zisofs-tools-1.0.8 into /shm/4G (cp -a) but
 ./configure
gave error message that a suitable C compiler was not found. So...
Use the flash drive to copy mkzftree from another 32bit Linux system that
has zisofs-tools-1.0.8 to the same directory as the script that wants it.
Note: 64bit binary gives error message "./mkzftree: cannot execute binary
file" when the script is run
 cp -a /shm/8G/mkzftree /shm/4G

Edit /shm/4G/custom-cd script
 vi /shm/4G/custom-cd
Tell custom-cd where to find resources
Path to bootcd.iso is /shm/4G  (I copied it via flash drive from the
computer that made the boot CD), so
 INPUT=/shm/4G/bootcd.iso
 ISO=/shm/4G/bootcdnew.iso
 MP="/shm/ISO"
 NEW=/shm/4G/NEW
 TEMP=/shm/4G/TEMP
Correct obsolete parameters of mkisofs
Modify -L parameter near end of shm/4G/custom-cd script to
-allow-leading-dots
Modify -P parameter near end of shm/4G/custom-cd script to -publisher
Add ./ path to mkzftree to tell custom-cd where to find it
 ./mkzftree $TEMP $TEMP.z

Copy notes on your progress to /shm/4G/NEW/doc if you want them on the
finished CD

Run the script
 cd /shm/4G
 ./custom-cd

Copy the new .iso to the flash drive. Take it to the machine with the CD
burner and burn it.

Disconnect the harddrive, boot the CD, enjoy grc.com reporting perfect
"TruStealth" rating.
