Package: lsb-base
Version: 3.2-16
Severity: grave
There is a bashism in /usr/lib/init-functions that breaks some init
scripts. For example checkroot.sh breaks when system is running on
battery power in log_warning_msg, this causes root fs munted read-only,
this also cases strange bugs after. So severity is grave.
The problem is that log_warning_msg does the following call:
log_end_msg -1
log_end_msg contains at the end of the function:
return $1
this gives:
return -1
That works in bash and zsh, for example. But it does not work with dash.
IEEE Std 1003.1, 2004 Edition says this about return built-in:
EXIT STATUS
The value of the special parameter '?' shall be set to n, an
_unsigned_ decimal integer, or to the exit status of the last
command executed if n is not specified....
(see http://www.opengroup.org/onlinepubs/000095399/utilities/return.html)
So dash is posix-compliant. Problem can be solved by using 255 instead
of -1.
