Does Linux Support Compressed Ext2 File Systems?

The ext2compr project provides a kernel patch Information about them
is located at http://e2ompr.memalpha.cx/e2compr/.

There is also a Web site for the e2compr patches. The code is still
experimental and consists of patches for the 2.0 and 2.1 kernels. For
more information about the project, including the latest patches, and
the address of the mailing list, look up the URL at
http://debs.fuller.edu/e2compr/.

zlibc is a program that allows existing applications to read
compressed (GNU gzip'ed) files as if they were not compressed. Look at
ftp://metalab.unc.edu/pub/Linux/libs/. The author is Alain Knaff.

There is also a compressing block device driver, "DouBle," by
Jean-Marc Verbavatz, which can provide on-the-fly disk compression in
the kernel. The source-only distribution is located at
ftp://metalab.unc.edu/pub/Linux/patches/diskdrives/. This driver
compresses inodes and directory information as well as files, so any
corruption of the file system is likely to be serious.

There is also a package called tcx (Transparently Compressed
Executables), which allows you to keep infrequently used executables
compressed and only uncompress them temporarily when in use. It is
located at ftp://metalab.unc.edu/pub/Linux/utils/compress/.
