It depends on what you want to change. Some system configuration items can
be changed while the system is still running. These generally fall into
one of two categories:
- System variables, such as whether or not IP packets will be gatewayed
between two interfaces.
These are adjusted using sysctl(8).
- Filesystems and compatability modules (I'm slightly generalizing) which
can be demand loaded. The modules are (typically) stored in /lkm, and
are loaded when necessary.
For example, my machine uses the CD drive infrequently. Rather than
compile the CD9660 filesystem into the kernel, I rely on the module to
be loaded when I mount a CD filesystem, and unloaded when I unmount it.

Unfortunately, this falls into neither of the above catgeories, and will
need a kernel recompile to do it.
