Bug#923478: initscripts use unsafe `: >` shell command to create files

[Thorsten Glaser]

Hi Pierre,

I’d say that aborting might be preferrable, but I checked your patch.

In the first case, it’s indeed preferrable to continue the init script
(and have the two additional error messages from chmod and chgrp, but
it continue on), and in the second case…

… this is true: the error handling does not get run.

So (from a shell maintainer’s PoV) these patches are good and should
be applied, in time for buster.

Thanks,
