Yes, but /dev/null has the disadvantage that you can read from it and
get EOF.  The advantage of redirecting from "/" (or from "nohup.out"
opened write-only) is that you get an error when you you try to read
from it (in most environments, anyway).  The idea is that a read error
is a better indicator to the user that stdin got shoved under the rug.
