Historically we don't handle this, because in opkg "installed_size" is
not tightly defined, so when installing it on e.g. compressed ubifs the
*actual* installed size is usually less than the size on e.g. ext2. The
fear was that package managers would refuse to install e.g. a 30MB text
file when ubifs reports 29MB free, even if that file would only occupy
3MB of actual space.

That's the background, I personally would like to include that (the
"uncompressed image size") info in the package, but I am unsure what the
implications are of that when using a recent opkg.

Koen
