# mksquashfs
sudo apt-get install squashfs-tools
# xorriso
sudo apt-get -y install xorriso
# /usr/lib/ISOLINUX/isohdpfx.bin
sudo apt-get -y install isolinux

Variables

FILE_ISO="Live-Raizo-v15.24.10.01i.iso"

# Not needed to be changed :

NEW_FILE_ISO="new_${FILE_ISO}"

NEW="new"
OLD="old"

DIR_FILESYSTEM="filesystem"

FS="${NEW}/${DIR_FILESYSTEM}"

---

Before Customization

• Create temporary directory :

mkdir -p "${OLD}" "${NEW}"

• Mount iso :

DIR_OLD_ISO="${OLD}/iso"
mkdir -p "${DIR_OLD_ISO}"
sudo mount -o loop "${FILE_ISO}" "${DIR_OLD_ISO}"

• Create a writable iso :

DIR_NEW_ISO="${NEW}/iso"
sudo rsync -X -a "${DIR_OLD_ISO}/" "${DIR_NEW_ISO}"

• Umount iso :

sudo umount "${DIR_OLD_ISO}"

• Mount filesystem :

DIR_OLD_FILESYSTEM="${OLD}/${DIR_FILESYSTEM}"
mkdir -p "${DIR_OLD_FILESYSTEM}"
sudo mount "${DIR_NEW_ISO}/live/filesystem.squashfs" "${DIR_OLD_FILESYSTEM}" -o loop

• Create a writable filesystem :

sudo rsync -X -a "${DIR_OLD_FILESYSTEM}/" "${NEW}/${DIR_FILESYSTEM}"

• Umount old filesystem :

sudo umount "${DIR_OLD_FILESYSTEM}"

---

Customization (examples)

• QEmu :

# VDI for VM
cp FILE.VDI "${FS}/opt/raizo/user/OS/QEMU"
cp FILE.VDI.md5sum "${FS}/opt/raizo/user/OS/QEMU"

• GNS3 :

# IOS
cp FILE.image "${FS}/opt/raizo/user/OS/IOS/"
cp FILE.image.md5sum "${FS}/opt/raizo/user/OS/IOS/"

# IOU
cp FILE.image "${FS}/opt/raizo/user/OS/IOU/"
cp FILE.image.md5sum "${FS}/opt/raizo/user/OS/IOU/"

# Config
cp FILES.CONFIG "${FS}/opt/raizo/user/Config/GNS3/"

• User :

# Config
cp FILES.CONFIG "${FS}/etc/skel/"

• fast-save-project :

cat << EOF | sudo tee -a "${FS}/opt/raizo/etc/cmd-fast-save-project.conf"
# Copy on the FTPs server : srvftp.domain.local :
net:ftps echo -n "Login : " && read LOGIN && lftp -u \${LOGIN} -e "set ftp:ssl-protect-data true ; put '%f'; exit" srvftp.domain.local
# Copy on the ssh server srvssh.domain.local :
net:ssh echo -n "Login : " && read LOGIN && scp %f \${LOGIN}@srvssh.domain.local:
EOF

---

After Customization

• Load parameters of LiveRaizo :

source "${FS}/etc/os-release"

• Change owner :

sudo chown -R 1000:1000 "${FS}/opt/raizo/user"

• Create new squashfs :

cd "${NEW}"
sudo mksquashfs "${DIR_FILESYSTEM}" new.filesystem.squashfs -comp xz -noappend
cd ..

• Create new live :

sudo cp "${NEW}/new.filesystem.squashfs" "${DIR_NEW_ISO}/live/filesystem.squashfs"
sudo chmod 444 "${DIR_NEW_ISO}/live/filesystem.squashfs"

• Create new iso :

sudo xorriso -as mkisofs -R -r -J -joliet-long -l -cache-inodes -iso-level 3 -isohybrid-mbr /usr/lib/ISOLINUX/isohdpfx.bin -partition_offset 16 -A Live_Raizo -p 'live-build' -publisher 'Live Raizo; https://sourceforge.net/projects/live-raizo/;' -V Live_Raizo_v${VERSION_ID} --modification-date=$(date "+%Y%m%d%H%m%S00") -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot -e boot/grub/efi.img -no-emul-boot -isohybrid-gpt-basdat -isohybrid-apm-hfsplus -o "${NEW_FILE_ISO}" "${DIR_NEW_ISO}"
