I'm definitely okay with quotearg-simple being relaxed, but I worry that relaxing quotearg may be counter-productive to protecting value-added of gpl code. On the other hand, it may be that the only reason quotearg is gpl is because it uses xalloc, and fixing it to avoid xalloc would then clear the way to make it usable from libraries. > xalloc > xalloc-die > xalloc-oversized Maybe xalloc-oversized can be LGPLv2+, but xalloc and xalloc-die must not be. Library code must not call exit(), and xalloc-die exists solely to call exit(). The xalloc module should remain GPL, and we should instead figure out how to break the dependency of quotearg wanting to use xalloc. -- Eric Blake ebl...@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
