The values are already "stored" in the OS in question, it do have track of
it's own lifespan, but of course not stored as a variable that is accessible
by the shell.

if the OP exports the value, they will only be in the shell he currently works
in, switching to another virtual console will just make that the variables in
question are empty as they never been set.
Of course it would be possible to set the values in ~/.bashrc, but then the
values will be different for each shell.

Not sure if the OP really thought about what he wants to do...
