Imagefish

What is this?

It's a bunch of scripts to create bootable linux distro images. I'm using it for both arm toys (raspberry pi) and for qemu.

It's a two-step process. First the distro is installed to a directory, then the directory is tar'ed up. This needs root priviledges, the scripts use sudo for that. Second the actual image is created, using guestfish. That works without root priviledges.

Optional third step is to tweak the image configuration, again using guestfish.

How to use this?

The most interesting stuff is in the scripts/ directory.

  • install-redhat.sh can install Fedora, RHEL and CentOS into a directory (first step).
  • tar-to-image.sh creates the images (second step).
  • various config-*.sh scripts can configure images (third step).

The repos/ directory has yum/dnf config files for various distros. They will not work out of the box for you as they are tweaked for my home network. They use either the mirror or the caching proxy running on my local server box. When fiddeling with this take care to keep the mkimage- prefix for the repo names.

The short scripts in the root directory call the scripts in scripts/ with different parameters to create different images.
