perhaps the check is too strict, but I'm not completely sure. A jail is 
safe if the rootdir of the jail is only writable for user root.

But I'm not sure about this: if the parent is writable for some other 
user (or group), he/she can for example rename the jaildir and replace 
it with a unsafe one, correct? If so that would make the jail insecure..
