Hello,

Yes, it works.
I am using it for several years now, with Centos 6, Centos 7, Centos 8,
Debian 10, Debian 11 and Debian 12.
In my case, bootable rear image is between 180 and 550 MB, depending
on the OS.

I didn't have to use it for real but all the tests I have performed were
successful.

It can restore the correct partition table with file systems and will 
boot
with the same IP address as the server that was used to create the 
image.

I managed to configure it the way that it can add bacula client and all
the needed libraries to the image.
The ReaR configuration to achieve that is quite complicated and there 
were
some limitations that I had to work around (without modifying the 
source).

I got the impression that it is not an easy task for ReaR developers to
maintain the code. Looks like bugs are easily introduced and hard to 
trace.

I have a bacula job that builds fresh rear image every month for all the 
servers
and a job called baremetal-restore which is meant to be used in 
conjunction with
a rear iso image.

The procedure for restoration using rear image in my setup goes like 
this:
1. get the newest bootable rear iso image from bacula
2. write the image to a bootable medium or use it as-is in case of 
virtual machine
3. boot the system using bootable rear iso image
4. use bacula director to initiate a bare metal restore
5. reboot the system

The idea was to make the bare metal restore procedure quick and easy, 
with the
hardware which is the same or similar to the original server.
