/etc/rc.d/jail writing hostname in /var/run/jail_example.id

[Nicolas de Bari Embriz Garcia Rojas]

After updating to 9.0 latest release (via cvsup) the /etc/rc.d/jail
cannot stop the jails after starting them

after debugging I notice that it the jail PID is stored on the bottom
of the /tmp.XXXXX

a quick hack is to edit /etc/rc.d/jail and replace the 'head' with a
'tail' on line 649 that looks something like this:

 _jail_id=$(head -1 ${_tmp_jail})

with this:

 _jail_id=$(tail -1 ${_tmp_jail})
