Booting Ubuntu Desktop amd64 liveDVD (3.8.0-19-generic)  in BIOS mode
searching "computer" using file manager to find sysreq settings is now
found in /etc/systl.d and named 10-magic-sysrq.conf.   Looking in my
Ubuntu partitionb which was last bootable using 3.8.0.28 kernel; also
confirms sysrq as being disabled by default Can not find why this has
been disabled as default so would like to take opportunity to ask; Why
is sysrq disabled as default on liveDVD?

Reading the original bug report refers to
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/194676  confirms
there may be secuity issues related to this.  Is it possible to ask for
some reasoning to this?  I thought linux had reputation of being secure
and virus free!?

Is not a better idea to have sysrq enabled to allow the well known and
used RSEIUB(O) if sytem hangs or freezes?  At least providing the
protection of minimising having to recover sytem files or data due to
corrupting hard drive and the need for fsck to kick in or be started
manually from recovery.?

Am asking these questions after watching 17 08 2013 episode of the BBC
programme
["Click"](http://www.bbc.co.uk/iplayer/episode/b0392vqy/Click_17_08_2013/)
and the "cyberwarfare" article really caught my attention. FAWC

Title:
  sysrq is now completely disabled, it would be nice to maintain the
  ability to reboot etc

Status in “linux” package in Ubuntu:
  In Progress
Status in “procps” package in Ubuntu:
  Fix Released

Bug description:
  In fixing Bug #194676 all of the sysrq functionality was disabled.
  Some options are of low security impact but aid debugabilty of
  systems.  It would be good to reenable what we can.  See the original
  bug for suggested values in use by other distros.
