And then you need not hide a file from root. That defeats a basic purpose of
exercise.
There is a partial way of hiding file from root. If you have any user mountable
partition, unmount the partition, copy the files to that directory and remount
the partitions. Now nobody can know that there are files on / which are not
under any directory. Of course if decided root can find this. So not exactly
full-proof but it's fool-proof upto some extent.
BTW, any idea if it's possible to use union mount under linux. IIRC that's
possible under freebsd. It's a great way of escaping from filling partitions.
You can be online without doing backup/partition/remount/restore loop.
