zisofs-tools
The zisofs filesystem is an extension to the ISO9660 filesystem that allows files, on a file-by-file basis, to be stored compressed and decompressed in real time. The zisofs filesystem is supported by recent versions of Linux (2.4.14 or later). Legacy systems can still read uncompressed files. zisofs-tools contains the tools necessary to create such a compressed ISO9660 filesystem and to read compressed files on a legacy system.

Recent commentsHard size limit
I am trying to master a LiveCD using zisofs. I have been very successful so far in creating many DVDs and have it scripted well. Is there a hard size limit of zisofs and/or the portion of the kernel that supports it? If there is not I believe I have a bug against one of them since the only thing I changed was the size (uncompressed) from 3.5GB to 5GB.

Thank you Peter and crew. Very useful tool!
Re: read from stdin
Tried to pipe from mkzftree to mkisofs without success.
Could not find a hint in the manpage and the web how to
to that if it is possible at all...
Re: read from stdin
% mkisofs "/tmp/isofiles" |
> mkzftree -F -
> result.iso
Doesn't really work... mkzftree is run before mkisofs, not after...
read from stdin
It could be great if mkzftree could read a file
(with -F) from stdin. Then I could use pipe like
this:
mkisofs "/tmp/isofiles" | mkzftree -F -
result.iso
It tries to open "-" as a real file instead of
replacing it by stdin.
