hi vda you are totaly right.
but Michael has a valid point:
/usr/local/sbin:/sbin:/bin:/usr/sbin:/usr/bin
IMHO this path should NOT include /usr/local/sbin.
system stuff is should always remain in
/usr/bin:/bin:/usr/sbin:/sbin
what is accidentally the default path.
if this is your idea we should include /usr/local/sbin AND /usr/local/bin.
