Query Regarding applications installed in base system

[bhargavacybervigilens-sys]

Scenario:
I installed the Wazuh agent in Status A using the command:

sudo apt install wazuh-agent

In Status A, the agent is available and running.

When I reboot into Status B, the Wazuh agent is also present, active, and running there as well even though I did not use any abroot command.

Given this behavior, what is the real use case of abroot, and in what situations would I actually need to use it?

apt is installing applications inside a container. This container is the same across both roots.

If you want to install a driver though, for example, it won't work inside a container, so you need to install it on the host. For this, you can use "abroot pkg", which will apply it to the future root so you will have to reboot to use it.

You can think of the it kind of like Android. You can install apps normally but to update the Android system you have to reboot.

Also, if you want to install something on the host that is not available through our repos, you need to create a custom image. The instructions for that are here:
