1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | Transparent decompression (-z option) is available on Linux kernels
using kernel version 2.4.14 or 2.4.9-ac14 or later.
You also need the zisofs-tools package, containing the mkzftree
utility, to create the compressed files; this package is available at:
ftp://ftp.kernel.org/pub/linux/utils/fs/zisofs/
The mkzftree utility can also be used to read compressed CD-ROMs on
systems which do not support transparent decompression.
The use of a separate utility allows compression to be controlled on a
per-file basis. A file which is not compressed can be read on any
system.
Transparent decompression is implemented as an extension to Rock
Ridge, so Rock Ridge needs to be enabled (-R or -r options.)
