There are a couple of ways of getting a compressed filesystem.  My favorite at 
the moment is zisofs, which is built into the 2.4 kernel.  There's also 
cramfs, the compressed loopback driver, and I vaguely remember some kind of 
ancient compression extension to ext2.
All of these are open source.

My understanding of the way upx gets its magical compression numbers is that 
the closed source version is probably pulling some tricks like stripping 
unnecessary elf sections, which don't really fall under the heading of a 
compression algorithm, and could cause strange side effects.  But it's hard 
to tell without source...
