NOW embedded linux gets SMALLER

Imagine getting Linux 2.4, glibc, Xwindows, Mozilla in to a
16M flash!
The "Compressed Block Device" CBD, a GPL driver, is a demand
decompression block device that shrinks file system partitions
2.5 to 3 times. Imagine getting linux 2.4, glibc, Xwindows,
Mozilla in to a 16M flash! The features include writable file
system, partition management, multiple base block devices, and known file system at reset time. The patch "cbd-2.4.0-2.patch.bz2"
contains the kernel patch and applications to use the CBD. The
offical device major is 102 accessed using /dev/cbd/a[1-15].
When using the CBD only the files being used are decompressed and in memory,
this means that memory is not wasted on unused programs and data. The big
difference between CBD and any other compressed file system is, that the
whole file system is compressed and is writable. The writes never get to
the physical device. So every time the system boots, the file system is in
always the same state.
The tools for making the compress partition and putting it on the physical
device are included in the patch and are under QPL.
