i need an easy way of cloning my current partition /dev/sda2
so other users can only extract this clone to their usb flashes
- maybe using a live cd , ubuntu for example -

if such a solution works fine, then users will have to install maxiboot loader and extract this clone to their flashes then we're done

now the problem is with /proc and /dev

they refuse to clone.

also using
dd if=/dev/sda2 of=/dev/sda3

doesn't work fine too

please help
