If your goal is to have uname(1) return the correct value, yes, except
it won't always work.  For instance, sudo(1) (and probably also su(1),
but I never use it) will strip it from the environment and will *not*
run /etc/profile before the requested command.

We can't assume that src is present.

Nobody suggested manually updating anything.
