[9fans] exit an rc script on any error; equivalent of bash's set -e

[Rudolf Sykora]

Hello,

is there anything similar to the bash's
set -e
(that causes a script to terminate whenever any command in the script
returns a failure)
in rc?
Or do I have to always write sth like
command1 || exit
command2 || exit
...
?
Thank you
Ruda
