No need for separate img and iso files. One ISO HYBRID file can do both. You can burn the ISO and also image the same file to a USB stick.
The reason why Webconverger has a commercial customisation service is that it used to be very difficult to make trivial changes to the boot command line.
The customisation steps are something like:
mount -o loop webc-6.1.iso /mnt/webc/
rsync -av /mnt/webc /mnt/custom
chmod +w /mnt/custom/isolinux/live.cfg
Now edit /mnt/custom/isolinux/live.cfg and change the boot command line
with your homepage URL.
Now rebuild the ISO like so:
mkisofs -o /tmp/custom-webc.iso -b -r -J -l -cache-inodes -allow-multidot -no-emul-boot -boot-load-size 4 -boot-info-table \
-b isolinux/isolinux.bin -c isolinux/boot.cat /mnt/custom
Finally:
/usr/bin/isohybrid /tmp/custom-webc.iso
isohybrid comes from a recent version of syslinux
The customisation service remains if you are unable to perform these commands. It’s also difficult to edit the package listing, such as changing chrome without the service still. For large deployments, please enquire with sales in how we can help you.
