The frysk package includes incredibly large core files as well as what looks like a number of apps statically linked with the same set of libraries. This leads to an on-disk footprint that's only less than that of openoffice!
I'll answer the corefile comment. Yes there is, but remember that a corefile is spares, so look at it via ls -lash and look at "real" size over "actual" size. It is actually needed to test all of the corefile functions, via the testsuite. Might move it to -devel instead?
The testsuite should get used at build time... it shouldn't really be needed to be installed at runtime. -devel maybe, but I wouldn't include it anywhere outside of the src.rpm
This is a known upstream problem. - the large executables, which are causing the large rpm size, will be fixed in frysk 0.5 (it missed the cut for 0.4). - the core files are (or should be) in the devel package and are used for testing / development. I posted a question about best practice for bundling tests to fedora-devel@, the only reply was a technical how-to. closing bug as upstream
