This is slightly misleading, I would change it this way:
```If enabled, this denies processes inside a chroot from issuing <literal>chmod</literal> or <literal>fchmod</literal>.``` -> ```If enabled, this denies processes inside a chroot from setting the suid or sgid bits using <literal>chmod</literal> or <literal>fchmod</literal>.``` (or something similar).

Otherwise it appears that a lot more software would be broken under a chroot :-)
