Yep. Happy days.

I say unto to you "ifconfig". And, frankly, _any_ sbin command which can 
be meaningfully run as nonroot, particularly for reporting.

I have always found this "oh its for root" distinction pretty vacuous, 
and outstandingly annoying when basic system querying stuff isn't in the 
default $PATH because of this.  Maybe it is because I've been a sysadmin 
for many years, but most physical machines are personal machines these 
days anyway - we're our own sysadmins.

Like modules with many names, the number of things in /bin or /usr/bin 
is generally irrelevant. Nobody does an "ls" in there without expecting 
a fair amount of stuff - like imports, we invoke commands by name. Who 
_cares_ how many names there are?

I have historically had to add it to my $PATH on most platforms.
