Substitute "posix" with "debian" and I'll agree: it is not a posix
issue, the init.d scripts are outside posix environment: they should
work also in a restricted environment (without some basic unix 
functionality). The issue was a busy /usr partition by shell
(when umount /usr), thus not always easy to solve and it could be again 
a shell design.

BTW it seems that all previous tries to remove the bug in bash failed.
