The Free and Open Source Software for Disk Imaging and Cloning

This release of Clonezilla live (2.5.5-38) includes major enhancements and bug fixes.


  • The underlying GNU/Linux operating system was upgraded. This release is based on the Debian Sid repository (as of 2018/Mar/30).
  • Linux kernel was updated to 4.15.11-1.
  • Partclone was updated to 0.3.11-drbl3 with some libraries updated. //NOTE// New image format is used in this release. It is different from the one saved by Partclone 0.2.x.
  • New massive deployment mechanism bittorrent was added. //NOTE// Clonezilla has to convert the original image to the special format when bittorrent mode is used. This will require more disk space in the image repository.
  • Switch keymap configuration method from console-data to keyboard-configuration. Ref:
  • Update language files de_DE, es_ES, fr_FR, hu_HU, ja_JP, it_IT, tr_TR and sk_SK. Thanks to Michael Vinzenz, Juan Ramón Martínez, Jean-Francois Nifenecker, Greg Hefty, Akira YOSHIYAMA, ianfranco Gentili, Volkan Gezer and Ondrej Dzivy Balucha.
  • Add channel bonding option when configuring network. Thanks to panther_1 for requesting this. Ref:
  • Make prep-ocsroot can use disk block device (e.g., /dev/sdc) as image repository. Thanks to Riksoft for requesting this. Ref:
  • Add options -pe and -pfe to ocs-sr. This allows user to enter password in the command options although it's not safe. Thanks to ub2 _at_ gmx ch for requesting this. Ref:
  • New compression lz4/lz4mt (-z8/-z8p) and zstd/pzstd (-z9/-z9p) were added in expert mode.
  • Make ocs-chnthn work for device name like /dev/nvme0n1p1. This change should really fix the issue reported here:
  • Remove "-p 16" for pigz in drbl-ocs.conf. It should let pigz to decide that automatically.
  • Package drbl-chntpw is no more used, and now we switch to use reged from package chntpw.
  • The file efiboot.img has been moved to /boot/grub/ from /EFI/image from /EFI/image/.
  • Add a workaround to make dnsmasq relay work for uEFI network boot clients. i.e., we have to assign the tftp server IP address in grub network boot loader. This is only necessary when dnsmasq is used to relay the DHCP request from clients to existing DHCP service. Ref:
  • Add boot parameter ocs_netlink_timeout so that the network link detection timeout can be assigned for ocs-live-netcfg.
  • Add an option -cbm to ocs-live-feed-img. Besides, remove boot parameter ocs_litesrv_mode. It's better to assign that in the command line option (-dm) when running ocs-live-feed-img, e.g., ocs-live-feed-img -cbm netboot -dm auto-detect -g auto -e1 auto -e2 -r -x -j2 -sc0 -p reboot -md multicast --clients-to-wait 1 --max-time-to-wait 300 start myimg sda.
  • Support using UUID and LABEL as image repository, i.e., local_dev for image repository can be assigned as: dev:///LABEL|UUID|PARTLABEL|PARTUUID=uuid|label. E.g., ocs_repository="dev:///UUID=84b012cc-5a4c-41e2-bf20-620d028072cb"


  • Jfbterm should not exit when lite server is running. It would terminate the required service for clients to restore image, especially BT service in non-English environment.
  • Cnvt-ocs-dev failed to convert EBR (like sda2-ebr). Thanks to killuaDK for reporting this:
  • Ocs-chnthn now supports modifying Win10 hostname. Thanks to František Griga for reporting this issue. Ref:
  • /EFI/centos/grubx64.efi should be before /EFI/Boot/bootx64.efi. Thanks to Fritzinger, Bernd (Bernd.Fritzinger _at_ bruker com).
