What the hell does this have to do with anything remotely relating to 
CentOS.

There is an FHS, almost all UNIX variants use it ... there is a reason 
for root to have a different path than normal users.

This is the document:
http://www.pathname.com/fhs/pub/fhs-2.3.html

If you want the standards changed, there are working groups to get it 
changed ... this is NOT one of those working groups.

Please take traffic concerning how screwed up the FHS is and how it is 
an old standard for an old time to the appropriate place.

If the FHS changes and removes /sbin and/or if the recommended paths 
change, then will change UNIX wide.  I can guarantee that if that 
happens, CentOS will also change.  I can also guarantee that as long as 
things stay the way they are, it is silly to discuss these changes on 
this thread.

Thanks,
Johnny Hughes
