Hi,
- the remastering of antiX is very simple with #live-remaster
- an bootable USB can be made easily with #live-usb-maker
But how can one create a single ISO for distribution?
Best, Robert

Best, Robert

Use the iso-snapshot program. It should work on live systems as well as installed systems. I know the closely related mx-snapshot program works on live systems.

If you are doing it on a live system then I suggest you place the output file (and intermediate files) in the pre-existing ~/Live-usb-storage directory (if it gives you a choice). This directory uses storage space directory on the live-usb file system so normally there is ample room there and it should be saved automatically across reboots.

We should provide you with a program that would make an iso file directly from a live system, thus avoiding the expensive mksquashfs step but we haven't gotten around to that yet. Maybe call it live-to-iso.

now that sounds interesting, how would an iso made directly from a live system avoid mksquashfs?

i use mksquashfs and id like to know what trick youre talking about-- even if its some kind of compromise or shortcut that isnt suitable for all use cases.

a simple explanation will do-- details are most welcome, though just a quality hint or two will probably satisfy my question.

When you are running from a live-cd, the live-cd is mounted at /live/boot-dev/. If you make an iso image of that directory (using genisoimage, or mkisofs, or xorriso ) then you will get an iso file that matches the one that was used to make the live-cd.

If you boot from a live-usb then it is almost the same and you can make a bootable iso image doing the same thing but first I would pull a few tricks to remove some live-usb things that don't belong in an iso file. The live-usb-maker program already uses these tricks to make a new live-usb when it "clones" a running live system. H'mm. I could probably add this feature to live-usb-maker with a dozen lines of code.

For now, you could probably run live-usb-maker from within a live-usb in clone mode. When it asks "Shall we begin?" then leave it waiting and make an iso file from the directory /run/live-usb-maker/iso/.
