upx is an executable kompressor it compresses files and adds a stub to do the decompression on execution. This would be an exelent idea for slow and preshus flash. would it be possible to get a script that cursess the bin directory
runnig this on all the executables.maybe we can do it on lib
as well. though there are cavets I would like to get some opinion on this

The flash filesystem (jffs2) is already compressed, so no point in using upx, unless you are running your system from mmc (ext2/3) which isn't compressed.

thanks i did a search i posted this question a couple of years ago I have a poor memory in my old age
