It is in my zsh shell, but here zsh is not involved at all.
For dash, it is not set by default:
francine:~> sh -c 'touch moo; echo blah > moo'
francine:~>
Anyway, I don't see why the noclobber option would have any effect
on the exec command, even when there is a redirection to a file:
francine:~> sh -c 'set -C; touch moo; exec true > moo'
sh: 1: cannot create moo: File exists
As you can see the error message is different. It is at the shell
level (before the "exec" command gets executed).
