Package: vlock
Version: 1.3-9
Followup-For: Bug #191963

Hello,

I figured out as well that the Magic SysRQ key can kill vlock.

I'd add to the voice of adding support for it in vlock, as it looks like
the stock Debian kernels have the sequence enabled:

$ grep SYSRQ /boot/config-2.6.16-1-686
CONFIG_MAGIC_SYSRQ=y

this means that vlock isn't locking the console on any default Debian
system.

Alternatively, one could ask the kernel maints to turn off the SysRQ key
by default.

Alternatively, I was wrong with determining that the sequence is enabled
by default :)

This can be implemented in a resilient way, with fallbacks if /proc is
not mounted and so on.  It could even be turned on with an extra
commandline parameter, like "vlock -a --sysrq"

Let me know if you would like me to provide a patch.  


Ciao,

Enrico
