Free drbl software for linux

Diskless Remote Boot in Linux in short DRBL is an open source environment to to manage GNU/Linux operating system deployment. Imagine the time required to install GNU/Linux on 40, 30, or even 10 client machines individually. DRBL will allow you to configure all of your client computers by installing just one server machine.
DRBL uses PXE/etherboot, NFS, and NIS to provide services to client machines, so you do not have install GNU/Linux on the harddrive of the clients. Once the server is ready to be a DRBL server, then the client machines can boot via PXE/etherboot (diskless).
"DRBL" does NOT touch the harddrive of the clients, so other Operating Systems (for example, M$ Windows) installed on your client machines will not be affected.
This may be important in a phased deployment of GNU/Linux, where users still want to have the option of booting to Windows and running Office. DRBL allows you to be flexible in your deployment of GNU/Linux.
Harddrives are optional for a DRBL client. The harddrive is just another moving part to fail or create more noise. If a harddrive is present, then the client can be configured to use it as swap space, while GNU/Linux is installed and configured on the centralized boot server.
Using the DRBL centralized boot environment, you can save a lot of time by configuring the client settings at the boot server. This gives the system administrator more control over what software configurations are running on each client.
Main features:
- Coexist with other Operating Systems
- Install one server, you have all clients ready
- Save hardware budget and maintenance fee
Enhancements:
- Use updated mkpxeinitrd-net, which allows assigning dhcp server name.
- Some bugs fixed. Check Change Log for more details.

Clonezilla Live is a Debian-based specialist live CD with software that enables users to clone the content of hard disks.
Main features:
- Free (GPL) Software.
- Filesystem supported: ext2, ext3, reiserfs, xfs, jfs of GNU/Linux, and FAT, NTFS of M$ Windows. Therefore you can clone GNU/Linux or M$ windows.
- Unlike G4U or G4L, in Clonezilla, only used blocks in harddisk are saved and restored. This increase the clone efficiency.
- LVM2 under GNU/Linux is supported.
- Unicast and multicast are supported in PXEBoot Clonezilla, which is suitalbe for massively clone. You can also remotely use it to save or restore a bunch of computers if PXE and Wake-on-LAN are supported in your clients.
- A single machine clone system without installation, Clonezilla live, is also available.
Enhancements:
- Now we can run a custom-ocs file n clonezilla live. A sample program custom-ocs which backup or restore /dev/hda1 to/from /dev/hda5 is in /opt/drbl/sample/custom-ocs.
- Use --menu instead of --radiolist in most of the dialog programs. Therefore no more pressing space bar to select the single choice.
- Update some comments, such as more comments about GNU/Linux device name to M$ windows device names.
- Debian iso template url and filename can be assigned in ocs-iso and ocs-live-dev.
- Bug fixed: device description was wrong when running prep-ocsroot in Clonezilla live (booting from CD).
