You're assuming the vendor supplied script will pick up the script
in /compat/linux. That, is not the case for the Portland Group
script:
if test -x /usr/bin/uname ; then
uname=/usr/bin/uname
elif test -x /bin/uname ; then
uname=/bin/uname
else
# Never seen it anywhere but /bin or /usr/bin, so hopefully it's
# in $PATH already.
type uname > /dev/null 2>&1
if test $? -ne 0 ; then
echo "install: uname not found in \$PATH environment variable"
quit
else
uname=uname
fi
fi
