NAME

mksacfs − make a compressed file system

SYNOPSIS

­disk/mksacfs [-u] [-b blocksize] [-o file] ­source

DESCRIPTION

­Mksacfs copies files from the file tree ­source (default .) to a the sacfs(4) file system archive file.

The files and directory structure are divided into ­blocksize (default 4096) byte blocks.  Larger blocks make large files more compact but take longer to access.  ­Blocksize must be at least 116.  If ­-u is given, the blocks are not compressed.  Otherwise each block is compressed using an efficient compression algorithm.
