Bind 9.3 rndc?

Hi,
have installed FreeBSD 5.3 with Bind integrated in it. named is running in 
chroot, with user bind, so every file in /etc/namedb is owned by 
bind:wheel, exept rndc.key. (i have also rndc.conf with owner bind)
and it is impossible to start make rndc reload. if i change owner on 
rndc.key it is working but is it a security issue, user who is running 
named (bind) to have acceess to rndc.key.
A another thing, if i make " sudo named stop/start" the own of my master 
folder is change to root:wheel (before bind:wheel)?
Any comment is appreciated.
