jails /boot directory in a jail gets filled up?

Hello,
I have upgraded a jail from the host with
% make installworld DESTDIR="jaildir"
now there are many files in the /boot directory. I believe this was empty before. My installation before the upgrade was two years ago and all the files in /boot have a new date.
I think it make no sense to keep this files because jails don't boot.

etcupdate has give a warning "Removed file changed: /boot/device.hints"
Can I safe delete all files in the /boot directory of that jail, which are comes with "make installworld"?
 
Jails use the host kernel, they don't have their own. They don't boot either. In theory, you don't even need the directory /boot.

But, looking at the ezjail way, a soft link boot exists between each jail and the base jail. Deleting this soft link does not prevent the jail to run. I can't tell if it is not used during update / upgrade or in certain special cases.
 
So I can delete the files in the directory /boot? I will keep an empty directory for updates.
