Manipulating the kernel

I didn't want to start a new thread for this, but I haven't stumbled across the answer otherwise...

If I, say, have no use whatsoever for SCSI drivers or SPARC architecture, might I simply delete the entire folder from the kernel's source?

In principle no, but before you delete them, have a look in the config file for compiling, you may have to edit so the compiler does not look for the files, because obviously if it does it will throw an error if it cannot find them.

And make a copy of the source first.
