how to build custom directory structure in freebsd

Question

we need to create our own OS using freebsd source code without any additional directories like /opt, /home and few. is there any way to remove directory structure creation from freebsd source code.

Answer 1

The most straightforward way is to write a post-install script that removes stuff you don't need.

You can also change the build system (Makefiles) to install things into desired locations, this is harder and will require additional work when updating FreeBSD source to newer version.
