The net-tools package contains the man page for etherwake but doesn't appear to contain the etherwake tool itself. Either the man page should be removed or the tool should be added.
Hmm, I can see it .. $ rpm -Vv net-tools | grep ether-wake ......... /sbin/ether-wake
But the man page is called "etherwake", not "ether-wake". Note the lack of a hyphen in the man page name. Also, the man page consistently refers to the tool as "etherwake" rather than "ether-wake". Either the man page needs to be updated or the tool needs to be renamed.
True, I've changed the manpage to refer correctly to ether-wake .. fixed in rawhide.
