I tested this script with bash, dash and even posh, and it works fine.

#!/bin/sh -e

unset no_such_variable1 no_such_variable2

Do you want to try again?

Subject: hotplug: /etc/init.d/hotplug stopped working because 'unset' fails

Package: hotplug
Version: 0.0.20040329-17
Severity: grave
Tags: patch
Justification: renders package unusable

"/etc/init.d/hotplug start" aborts almost immediately, it doesn't even
print the "Starting hotplug subsystem" message. I didn't notice this
until I tried to use an USB device and found that no USB modules
were loaded. Other modules like hw_random had not been loaded either.

I've tracked it down to an 'unset' call failing, apparently because the
variable to be unset hasn't been set in the first place. This simple
patch made it work again:

Not my version of bash (nor dash, nor posh), and the man page agrees:

    The exit status is true unless a name is readonly.

Looks like this was changed in bash 2.05b-beta1. Can you confirm that
your version is older?
