/usr/sbin/netstat should be included in primary.  Looks like a packaging error.  Can you query metadata?

Installing /bin/netstat works:

$ sudo yum install /bin/netstat

Nothing to do

Also:

$ ls -ld /bin
lrwxrwxrwx. 1 root root 7 Nov 22 15:40 /bin -> usr/bin

So it's something broken by UsrMove, I guess.

Interestingly, this doesn't work on Fedora 18 either.

This is indedd UsrMove braindamage:

[pmatilai@localhost tmp]$ rpm -qpl --nosignature net-tools-2.0-0.2.20121106git.fc18.x86_64.rpm |grep bin/
/bin/netstat
/sbin/arp

/sbin/ipmaddr
/sbin/iptunnel
/sbin/mii-diag
/sbin/mii-tool
/sbin/nameif
/sbin/plipconfig
/sbin/route
/sbin/slattach

Those are the only paths that yum will recognize for those files, although they do of course end up in /usr/bin in practise. "Fixing" this would require net-tools to install them into /usr instead, but that in turn will break any packages that have dependencies on the current /[s]bin/ paths.

I thought yum had been fixed somehow so that either path worked?
At least, that was my recollection ...

Nope. On rpm level symlinked paths can be interchanged for already installed packages, but for to-be-installed packages its ultimately an unsolvable issue:

On an already installed system, the other direction (specifying /bin/telnet where the actual file owned by telnet package /usr/bin/telnet) could be easily handled with realpath(), but going "backwards" is a good deal more complicated. And neither direction is "translatable" when the directories are not present on the filesystem, such as on initial installation into chroot.

It *is* a bug, it's just that you won't or can't fix it.
