You can avoid the command substitution fork by using read:
{ read redhat_release < /etc/redhat-release; } 2>/dev/null
Whether that's deemed any simpler, though, is a matter of taste. Not to
mention that use of 'read' like this is limited to cases where you know
you are reading a one-line file (when present).
