Re: [coLinux-devel] Minimal Fedora Root

[Jaroslaw K. <ja...@zd...>]

I liked the idea of having sparse image files so much that I created a tool
for decompressing *.bz2 and making the result sparse at the same time:

http://jaak.sav.net/colinux/sparsify.exe
(source is here: http://jaak.sav.net/colinux/sparsify.cpp)

Usage:

bzip2 -cd image_file.bz2 | sparsify.exe image_file

It will print "#" for each non-zero chunk and "." for each all-zero chunk.

BTW. CoLinux works like a charm with these sparse files!
BTW2. Bzipping with "sparsify.exe" is actually faster than normal because
fewer disk blocks get written to the disk.
BTW3. Untested with really large images (over 4GB) but should be fine.
