jails There is a way to make the FreeBSD's subsystem for Linux to only apply in the boundaries of a specific Jail

[Ferocious1881]

I am moving my homeserver to FreeBSD away from Linux, but some services look like cannot work with FreeBSD, I have plans to install those services in a Linux jail like here https://it-notes.dragas.net/2024/01/18/installing-alpine-linux-on-a-freebsd-jail/, but I would like the compatibility layer to only be active when inside the Linux Jails and not outside of the Linux Jail.

Is this possible?

Jails run on the host's kernel. The host kernel has the compatibility enabled.

In technicality terms, meaning technical feasibility, this does not make impossible to have the linux compatibility layer only enable in a jail, as the host kernel may have the ability to be configured to only apply the compatibility layer when the syscalls come from a specific jail.
