Compression file system

#include <sys/filio.h>
#include <sys/fs/decomp.h>

The dcfs filesystem is a layered filesystem that you use to compress data when writing to a file and decompress upon read. The primary function of the dcfs filesystem is to compress individual files when constructing a boot archive and when reading or booting from the archive.


boot(1M), bootadm(1M), fiocompress(1M), attributes(5), ufs(7FS)

The dcfs compression/decompression file system works only with UFS.
