Of co= urse we also can think of additional knobs, but there is an issue - it wont= help just to exclude some files, the additional features also do sit in th= e code, so the replacement stubs will be needed, also testing them all over= will take some time.

In the future, maybe it'd be a good idea for the installer to leave more space (a few MB, perhaps?) between the freebsd-boot and freebsd-swap partitions? At least, for ZFS installs.
