Yes, this is part of the issue, people in this forum are quite happy to help solve problems, so if you have a problem come forward. If however you have no acute problem, why waste everybody's time?
Most folks here know, that OpenWrt being a linux distribution tailored to low-end devices does not offer everything big Linux distributions offer, so enumerating all differences seems moot unless such a difference causes real problems ;), but then it helps if the problem is stated along with the difference that makes solutions for "normal" linux distributions inapplicable for OpenWrt.
Because I am happy tp spend some time helping with a problem, but not with non-problems
The why is missing, someone less conscious of the dangers of removing a piece of kernel code where other parts of the same kernel might still hold references to than you, might get wrong ideas about when calling
rmmod --force my_module is reasonable. (I admit that
modprobe -r seems less dangerous in that it tries to also remove the reference holding modules, but that is subtle).
