Re: Security skills
Of course it is, assuming we're comparing a standard school image to an OOB Linux install (apples, oranges does come to mind though). We managed OK on Windows machines though, but did have the 'benefit' of DOS before that..
You're right though, that the core problem is the way the curriculum has taken all the fun out of it. It does it in every area though, I remember being told you can do that if you want, but they won't give you any marks for it, only bits x, y and z will be marked where x,y and z were the most boring unimaginative things you could think of.
Part of the problem is, again, lack of skills. Most teachers aren't going to be happy to let the kids do something they themselves don't understand (unless they have to), which at the moment will generally cover everything except spreadsheets. Again, part of it comes down to pay, with the skillset I have I wouldn't dream of having to deal with a classful of kids for what teachers get, never mind dealing with the difficult parents.
