I have no idea. You tell me.

It is actually a very unreasonable place for sh. /sbin should not be 
read as a place for statically linked binaries, but a place for binaries 
that are needed for systems work, but not binaries a normal user would 
need, and binaries that are needed before you mount anything.

Shells do not belong there, and in the specific case of sh, it is a more 
or less very established standard that it should be in /bin, and lots of 
scripts depend on it, having #!/bin/sh as the first line in the scripts.

If you were to move sh to /sbin, your system would mostly start failing, 
I can promise you. But feel free and go ahead and test it.

Next I'll guess we'll be discussing the difference between /usr/bin and 
/usr/sbin as well. And then all the different ideas what should be in 
/lib, /usr/lib, if you should have a /usr/libexec, if you should have 
binaries in /etc, what /use/local should be used for, and all the other 
places that are confusingly used by different systems.

Well, if you know, how about you enlighten us?

Oh gee... As if I didn't say that every flavor has its own ideas on how 
to do things... Are you now saying that I'm claiming that Unix should be 
a specific way?

I'm surprised that you want to fight with me about it.
Why do you want to pick a fight with me?
