Currently, I have selected a distribution of Linux that I like a lot and I have downloaded the .iso image which I can simply
dd to an USB or CD media, etc...
I would like to add some additional data to this installer image so that I do not have to bring both a installation disk and removable media with me whenever I need to setup a machine.
Is this something that can be done? If not, how would I go about creating a reasonably sized and bootable iso file after compiling an operating system from source?
I have experimented with mounting the iso file, copying all the files out of it, and trying to repackage it all back into an iso again; however, this resulting image is not bootable.
I am hoping to glean what it is that makes a bootable iso so special when compared to a normal CD with files on it.
