NAME
newlfs - construct a new LFS file system

SYNOPSIS

The following options define the general layout policies.

-B  The logical segment size of the file system in bytes.

-b block-size
    The block size of the file system in bytes.

-L  Create a log-structured file system (LFS). This flag is currently required.

-s size
