If `AUTOMAKE` is set to `no` in the config file, it is normalized to the empty string. This leads to two errors if `find` is provided by Busybox. There is a conditional where `$AUTOMAKE` is not quoted when compared to `recursive` leading to the following error: /usr/share/shorewall/lib.cli-std: line 398: [: =: unary operator expected In contrast to the non-Busybox case, we don't check for an empty `$AUTOMAKE` before passing it as an argument to `-maxdepth`, leading to: /usr/bin/find: Expected a positive decimal integer argument to -maxdepth, but got -type Refactor the conditionals to eliminate code duplication and fix these two bugs.
