How to quickly deploy a customized Linux OS to new computers over a network?

Question

linux

Good afternoon. A new fleet of cars has arrived (30 pcs). I was tormented to assemble from kits: D You need to deploy OS Rosa Fresh for everyone, but installing and configuring each one will take a lot of time. I found on the net a program for bit-by-bit copying of a UDPCD hard disk . Ran a test deployment in VBox. The system got up normally, the copy speed was 150mbps. I started copying the system to live machines (1TB disks) and ran into a problem - speed 4.5mbps
Motherboard - GA-H110M-S2
Seagate BarraCuda ST1000DM010 disks Tell me
how to configure the program for higher speed, or how to deploy by other means.

Answer 1

Network installation (tftp) and policy configuration (Ansible, etc.)

Answer 2

clonezilla.org/clonezilla-SE - can act as a deployment server with network boot support. You need to configure your clients to boot over the network as the first item in the BIOS. Well, make a natural image.
Details - drbl.org/installation , clonezilla.org/clonezilla-SE
Here's another option - https://fogproject.org

Answer 3

clonezilla

Answer 4

all Linux distributions can be installed over the network, for example, via PXE

Answer 5

You install the system and set it up for one basin, then you take Acronis True Image, create an image and upload it to ftp. And then with the help of the same True Image you unfold. It took us about 2 days for 300+ PCs.

Answer 6

load the target basin from a liveCD of any Linux, raise ssh on it,
look at which disk the system is installed on the reference system and how it was determined on the target (where the LiveCD is),
then on the reference we execute the command
dd if=/dev/sda | gzip | ssh [email protected] "gzip -d | dd of=/dev/sda"
/dev/sda - substitute your own
123.123.123.123 - IP address of the target system (LiveCD)
But it will take a long time, given the size of the disks
