This is probably a rather minor problem, I guess. The presence of this support could be used to tie-break otherwise equally good solutions but is probably no show-stopper. > 2) I'm not sure what os distributions think about these paths in general This point is explicitly adressed in the FHS, which is the closest thing to a standard in the Linux world for these matters: (I’m lazy so I quote Wikipedia): /var/lib State information. Persistent data modified by programs as they run, e.g., databases, packaging system metadata, etc. https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard The idea a system of what should go in this directory is probably only relevant if we use /usr or /usr/local as OPAMROOT, but for other prefixes we should be relatively free to do what we want – but mirroring the hierarchy used in the own’s OS prefix is probably a good thing here. _______________________________________________ opam-devel mailing list opam-devel@lists.ocaml.org http://lists.ocaml.org/listinfo/opam-devel
