Re: vlock + magic SysRQ key

[tim () NIGHT-SHADE DEMON CO UK (Tim Fletcher)]

Following an email exchange with the Slackware maintainer Patrick J.
Volkerding <volkerdi () slackware com> he put the Magic SysRq in all the
prebuilt kernels shipped with slackware 4.0. I guess this was a bad idea
on my part.

I would still like to see Magic SysRq in install disk kernels as it helps
to debug installs that die.

Also I note from the 2.2.11 changelog that Magic SysRq can be runtime
enabled / disabled

Thou the kernel src tree from Slackware 4.0 is pristene 2.2.6, so any home
make kernels will have the SysRq turned off by default
