watch(8) does not work in jails

I enabled `device snp' in my kernel config file and with this I can
use the command watch(8) to see any tty device attached. For example :
# watch ttyv0
Give me the output of the console.
But in jails, it's not the same thing, I tried the following :
# jexec 1 tcsh
# su -
People# watch pts/0
watch: fatal: cannot open snoop device
Is there a limitation of watch(8), or jails ?
