 They are. You might prefer the former style if you're
performing one or more instructions before the final exec,
all of them with 2>&1 ; but it's a matter of taste.

 Anyway, the best way to write your script is obviously the following:

#!/command/execlineb -P
fdmove -c 2 1
supervised_command options parameters
