Hi.

I abandoned creating my own bootable ISO (Debian) when I experienced restrictions in the creation process.

Is it possible to create a file (ISO or other) from a linux partition, as is without restrictions to boot and run from, and function regularly as if it were running from the partition ?

I don't want to create a new partition every time for another linux OS. I know this is easily acomplished via Virtualization but I would like to know if I can acomplish my objective by rolling my own file to boot from with persistance.

Thank you.
Serene

If I understand what you're after correctly - have your tried Linux Live yet?

Thanks for the tip, looks like this may be what I'm looking for.

I was hoping there would be a more direct migration approach without using 3rd party scripting.

Best regards,
Serene

You can't simply copy your root filesystem to an ISO image because Linux expect the root filesystem to be writeable. So you have to jump through a few hoops, the script just lines the hoops up for you into a single jump.

Yes, understood about copying directly, thanks.

My hopes are that the script allows full retention of your installed system, unlike a preparation of a Debian Live CD/DVD.

Cheers
