=================

> Note: This is a POC!

A guestfs based edit-node.

This is how it works:

1. guestfish is used to extract the ext3fs.img from an existing LiveCD ISO

2. guestfish is used to run a script inside the ext3fs.img (which is mounted inside a VM)

3. Classic tools are used to rebuild the LiveCD ISO (TBD)

Usage:

    edit-iso.sh   []

Where

* `isoname` is the path to an existing ISO.

* `cmd` is a predefined cmd - a list of comands is printed when you don't provide a ``

* `cmdargs` (optional) Some commands take arguments (like `yum-install`)

Example:

    sudo setsebool -P virt_use_fusefs 1

    edit-iso.sh  info

Will print some informations about the iso (system-release and ovirt rpms)

## Notes

* `setsebool -P virt_use_fusefs 1` needs to be enabled to allow guestfs to mount nested images

* This might not work on RHEL because guestmount is used - which in turn uses FUSE

* This tool does not yet require root rights, as the VM is spawned in a qemu session
