jail stop extracting iso file

[tethys ocean]

İ see, i should extract this iso image (not using tar) may i close this
jail? and can i restart correctly? i am hesitate since squid in running on
jail? process is like

[root at finn /etc]#  ps ax -o pid,jid,args
  PID    JID COMMAND
 8415      0 /usr/local/sbin/httpd -k start

[root at finn /etc]#


i think so i can stop jail by this command? (but it run)

/etc/rc.d/jail start
/etc/rc.d/jail stop


OR i can kill jail process and than /etc/rc.d/jail stop  and i can disable
in sysctl jail line

#security.jail.set_hostname_allowed=1
#security.jail.socket_unixiproute_only=1
#security.jail.sysvipc_allowed=0
#security.jail.enforce_statfs=2
#security.jail.allow_raw_sockets=0
#security.jail.chflags_allowed=0
#security.jail.jailed=0

than extract iso  file and restart jail?  possible? and it contains any
risk? since squid is so so important

since i ve read  this paper
http://www.freebsd.org/doc/en/books/handbook/jails-application.html

but i wasn't able to find some jail details/setting in this server but
neverthless jail is running

regards
