is it Ok to strip kernel modules?

2014-03-25 Thread Lev Serebryakov
Hello, Freebsd-current.

 Why our kernel, even built without DEBUG, is not stripped? It could sabe
1.5Mb out of 8Mb for router-like (network, wifi, some netgraph, UFS, NFS and
USB) kernel...

 But maybe, here are some reasons not to strip it?

 Assume, I don't want use dtrace, ktrace and kernel debugger.

You could strip the modules no harm done.

If you strip the kernel, then you won’t be able to use anything that opens up
kernel memory to read answers out of it. I think this is all wrapped in ksyms, 
so
you could grep for it. Be thankful that ifconfig no longer is on this list :)
