As it is right now, these programs rely on the the corefile code finding the executable in the elf_prpsinfo notes. However things like: ./foo/bar/exename Will defeat it as "./" means nothing to the code. This code is exceptionally fragile and should not be used until --pivotexeroot and --pivotsolibroot are implemented. There are two constructors in dead/LinuxHost, one of which where one specifies both the corefile and the executable.
