[Tails-dev] Unique Hardware Information

If someone can get an shell on Tails, they can get a lot of hardware
information without root. Dmesg is stopped, but any user can run 'cat
/proc/cpuinfo' 'lsusb' and 'lspci', which makes it easier to identify
the user. Someone can use something like a Firefox exploit on the unsafe
browser to get a shell. Is there a way to stop regular users from
getting this info?
