/sbin not in path in su?

[Mike Evans <mike@xxxxxxxxxxxxxxxxxxxxxx>]

Sorry if this has been covered... I'm new to the list and the search 
function in the archives is non-op.  After a brand new install of Fedora 
Core 1 on my Thinkpad R40, I was trying to compile some drivers and 
noticed that all the errors and warnings that cropped up were related to 
the script not being able to find "ifconfig"

Since ifconfig is in /sbin and I was su, why wouldn't /sbin be in my 
PATH?  I'm not only confused about that, but how to remedy the 
situation.  Thanks for the help.

Mike
