AFAIK there's only one gzip version as such (GNU zip), and there are some clones. I think it's safe to expect that clones are always format-compatible with the original GNU implementation. Btw, GRUB 2 already supports gzip files, see io/gzio.c. -- Robert Millan <GPLv2> I know my rights; I want my phone call! <DRM> What use is a phone call, if you are unable to speak?
