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
