Package: alsa-base
Version: 1.0.8-4
Severity: normal
Tags: patch
The alsa initscript uses
eval $1 --help || ...
to test the presence of a command "$1". However the behavior
of `eval foo || bar' after `set -e' is shell-dependent,
see Bug#268944.
If /bin/sh is dash, and the command in question is amixer,
the script fails immediately due to `amixer --help' returning
exit code 1, and dash's poor handling of eval. If /bin/sh is bash,
the function correctly finds that amixer is present.
While this is arguably a bug in dash and a bug in amixer (non-standard
handling of --help), it's better to avoid this kind of testing in
initscripts. Removing `eval' fixes the problem - its argument
is not going to be expandable anyway.
