Could you explain this? Firstly, I'm not aware of performance improvement or degradation arising from the use or non-use of modules per se - however, I've never gone looking for it. I've always used modules for their convenience value, rather than their ability to make my system go faster or slower. Information on this would be interesting. I'm interested to know about security implications of the kernel module system. Presumably you're thinking of a scenario where an attacker gets sufficient privilege to replace mymodule.o with a malicious mymodule.o, therefore gaining some nefarious ability. Well, while not totally unfeasible, this scenario is unlikely and doesn't bother me for the following reason: if you've been rooted, you're looking at nuking the system and restoring data anyway. However, there might be more subtle aspects to this that I don't get. Wouldn't be the first time :-) Regards Peter. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
