This is exactly how I do things.  I've got a whole folder of "special 
scripts" that require su.

But getting the script developed usually requires some experimenting as 
root to get the right order down and verify that it works.  I see that 
as a whole lot safer than just writing the script from scratch and 
sudo'ing it and hoping it works.  Just me though.

To further bastardize the analogy, sometimes rock-climbing with scissors 
is necessary, but if you don't hang a pulley system when you get to the 
top and use that from then on to lift the scissors up and down the 
rock-wall, well, you're just asking for it.

Best,

ellis
