Bang on target till here....

Nopes bsdlabel is for something else. By default the new kernel gets
installed. No need to update anything in the boot block. If you ned to
boot the old kernel then Hit any other key when it says:
hit [Enter] key to boot kernel
then boot /kernel.old
And you will be back with your previous kernel.

Refer to /usr/src/sys/i386/conf/NOTES and /usr/src/sys/NOTES if you
are on 5.* and /usr/src/sys/i386/conf/LINT for the driver.

Well hard luck. Jail is something like FBSD inside FBSD but it is not
completely FBSD inside FBSD. They run the same kernel and not two
separate copies of it. What you need is vmware.

I guess you know the reason by now
