#235795 — Create Live image from installed Debian?

Folks;

been playing with MX Linux lately on a virtual machine and enjoyed its 
"snapshot" feature which apparently allows for creating a bootable / 
installable Live image of my installed system.

As I usually configure and tweak my Debian systems a bit, too, 
especially for desktop purposes, I wonder: Is something like that 
available for Debian too? How to do so best, if at all?

Thanks in advance and best regards,
Kristian

It creates a bootable ISO and you can restore from this ISO.

However, your ISO must fit on DVD, CD or BlueRay. I did not test it, but maybe 
the ISO can be installed ión an USB-Stick, too, so your bootable system may 
fit on it. If this workls, that should also work with USB-harddrives.

God luck!

Hi,

In my role as curious bystander i follow this advice.

Using tracker.debian.org i get to
  https://sources.debian.org/src/bootcd/6.4/FAQ.backup/
which promises indeed

  "The bootcdwrite command creates a life-cd with your actual debian
   system."


> your ISO must fit on DVD, CD or BlueRay.

Blu-ray is at 100 GB max meanwhile (for the price of your soul).
25 GB is quite cheap.

It looks like that.

From tracker via codesearch.debian.net i get to
  https://sources.debian.org/data/main/b/bootcd/6.4/bootcdwrite.lib
where i see

   ia_add "MKISOFS_OPTS=\"-z -R -graft-points -quiet \
  -isohybrid-mbr /usr/lib/ISOLINUX/isohdpfx.bin -c isolinux/boot.cat \
  -b isolinux/isolinux.bin -no-emul-boot -boot-load-size 4 -boot-info-table \
  -eltorito-alt-boot -e EFI/efi.img -no-emul-boot -isohybrid-gpt-basdat\""

MKISOFS_OPTS gets used with  xorriso -as mkisofs .
They are much like in debian-cd, i.e. suitable for booting from optical
media and from disk-like devices: USB stick, hard disk, SSD, memory card.
The options target boot firmware of both, legacy BIOS and EFI.


Have a nice day :)

Thomas

Cool, thanks very much, I'll have a look and see how far this gets me. :)

Best,
