Current Directory in root's Path / Current Directory in Path of Regular Users
Whenever a program is called without specifying the full path to the executable,
the system looks in the user's search path (defined by the variable
$PATH
) for the
executable. By default the current directory is not added to the search path. This
setting ensures that, for example,
/bin/ls
and not the trojan horse
/ current
directory /ls
is executed when entering
ls
. In order to start a program in the
current directory the command must be prefixed with
./
. When activating these
options, the current directory (
.
) is appended to the search path. It is recommended
you not change the default.
Enable Magic SysRq Keys
The magic SysRq key is a keycombo that enables you to have some control over
the system even when it has crashed. The complete documentation can be found
at
/usr/src/linux/Documentation/sysrq.txt
(requires installation
of the package
kernel-source
).
