hi kai,
while in permissive mode, selinux just reports policy violations of the avc .. but doesn't block the action.
the symlink in /etc/sysconfig should point to /etc/selinux/config and not to /etc/syslinux ..
if selinux is disabled, /selinux/enforce does not exist what does the output of `getenforce` tell you ??
btw: are you sure that selinux is the problem ??
